History of the Danish Mycological Society (4) – 1980-2005 - Flemming Rune - 51:1-21.
The introduction of the journal Svampe in 1980 led to a new popular trend in the Danish Mycological Society. Consequently, the membership almost doubled in the first half of the 1980’s and settled at about 1800 for the next twenty years. The number of mushroom forays increased tenfold from 1978 to 1988, and more than 100 forays annually became standard. Eight groups of members in different parts of the country became responsible for forays, courses and exhibitions locally. Since 1979 forays have also been arranged in e.g. the Mediterranean, Russia, and Eastern Europe. In 1982 the society introduced a diploma examination in ‘proficiency in macrofungi’ to ensure proper qualifications among foray leaders. So far 161 diploma holders have been certified. A number of important macromycological works were published in cooperation with various publishers. In 1990 the first complete Danish field guide to basidiomycete macrofungi with keys to some 2100 species was edited by Jens H. Petersen and Jan Vesterholt. The book series Fungi of Northern Europe presenting popular monographs of fungal genera was initiated in 1995, comprising Hygrocybe and Lactarius in the two first volumes. MykoKey, a CD-rom and internet based synoptic key to 528 basidiomycete genera worldwide with more than 2000 colour photographs was published in 2003, and in 2004 a comprehensive book with 1000 colour photographs of Danish macrofungi followed.
Different working parties in the society are in charge of nature protection matters, vernacular nomenclature for fungi and management of the society’s charity grants. Since 1997 the homepage www.mycosoc.com has been the most important site for exchange of information between members, with databases of names, records, red-listed species and lists of activities. During the period 1980-2005 four members have served as presidents of the society: Hjørdis Hall Andersen, Jørgen Albertsen, Jan Vesterholt, and Flemming Rune.

Dyeing with mushrooms - Susanne Thorbek & Preben Graae Sørensen - 51:24-27.
The first public exhibition in Denmark demonstrating how to dye textiles with colours extracted from mushrooms was organized by Hjørdis Hall Andersen in Sorø in 1985. The inspiration came from a book issued in 1974 by Miriam Rice from California „Lets try mushrooms for Color“. Dyeing with plants and lichens is an old tradition in the Nordic countries dating from the Vikings. Although artificial chemical dyes with brilliant colours are now available, the delicate scales of colours from plants and fungi make these particularly suitable for artistic work. The most popular fungi used in Denmark are Cortinarius semisanguineus and C. sanguineus (red), Hapalopilus rutilans (violet), and Phaeolus schweinitzii (yellow to brown). From August 23 to 28 in 2005, which is the 100th anniversary of the Danish Mycological Society, the 12th International Fungi and Fibre Symposium is organized in Haslev, Denmark. Information and procedures for participation can be obtained from the homepage of the Danish Mycological Society.

Fungal names 1: Danish vernacular names for non-agarics - Poul Printz - 51:28-31.

The world’s largest and most precious truffles - Flemming Rune - 51:32-35.
During 2003 and 2004 truffle prices surpassed the wildest expectations at three large truffle auctions in Italy. Three giant Piedmont Truffles (Tuber magnatum) weighing up to 1050 grams were bid up to as much as US$ 52,000. The auctions were transmitted by satellite to the USA, Britain and Russia, and the income was donated to various charity projects. The most expensive truffle was bought by a London restaurant and exhibited for five days. Finally, it turned bad before use. A delegation from Toscana brought the truffle back to the place where it was found and gave it a ritual funeral ceremony. The largest Piedmont Truffle ever was found in 1954. It was unearthed in Toscana only 5 km from the new price record-breaking truffle, and had a weight of more than 2500 grams. It was offered as a present to the American president Dwight D. Eisenhower.

Cortinarius aureocalceolatus – new to Denmark and Northern Europe - Tobias Guldberg Frøslev & Thomas Stjernegaard Jeppesen - 51:36-37.
Cortinarius aureocalceolatus is reported as new to Denmark and Northern Europe, where it grows with Fagus on calcareous or mineral rich soil. ITS-sequences of the Danish collections correspond 99,84% with those published from the type (GenBank Access Nr.: AF503543). The root-like attenuated stipe is stressed as an important diagnostic character, not found in the original diagnosis.

Volvariella bombycina in unusual circumstances - Leo de Jong - 51:38.
An indoor habitat is reported for Volvariella bombycina: a concrete floor near a leaking pump underneath a swimming pool.

A preliminary study of Danish Laboulbeniales on carabid beetles - Jimmie Høijer & Lykke Hjorth Mikkelsen - 51:39-47.
A preliminary study on Danish Laboulbeniales on beetles trapped in pit falls (216 specimens, 29 species) at three sites was carried out. Five fungal taxa were recorded: Laboulbenia fasciculata, L. aff. fasciculata, L. aff. flagellata, L. peudomasei, L. cf. pterostichi. In the case of L. fasciculata all beetle individuals (Patrobus atrorufus) were infected, whilst much lower infection rates were found in other cases. Six species of Coleoptera were infested (38 individuals).

New Lepiotas for Denmark - Henning Knudsen - 51:50-55.
Three species of Lepiota, viz. L. parvannulata, L. rufipes and L. forquignonii are reported for the first time from Denmark and descriptions are given of the collections. The record of L. forquignonii is based on a plate in the Botanical Garden & Museum in Copenhagen by the late F.H. Møller. L. parvannulata was found in a shrub of Prunus spinosa close to the sea, in a sand-mixed soil. L. rufipes ss. str. was found in the Botanical Garden in Copenhagen under a Thuja orientalis in a small bed of fine wood chips and in southern Sjælland on a lawn in a garden under Quercus. Additionally, some new records from Denmark are given of the rare and recently recorded L. ochraceofulva.

Notes on rare fungi collected in Denmark - Jan Vesterholt (ed.) - 51:56-59.
Mycena juniperina is reported as new to Denmark. It was found on twigs and branches of Juniperus. The characters separating M. cupressina from M. juniperina do not seem fully convincing.
Entoloma depressum was described recently from Danish material. Additional information is given about the type collection and the type locality.
Phaeocollybia christinae was found on two different localities on Bornholm in 2004. It was last reported from Denmark in 1927.

A defense for puffballs - Annette Wium - 51:60-61.

The mushroom dye artists at the Pacific - Flemming Rune - 52:1-7.
During winter 1972-73 a bumper crop mushroom season along the Pacific coast in California inspired the artist Miriam Rice in Mendocino to investigate the potential of fungi for textile dyeing. Hypholoma fasciculare was the first mushroom she tested, but two years later more than 50 more species had proved to be useful for dyeing. Her two books ‘Let’s try mushrooms for color’ (1974) and ‘Mushrooms for color’ (1980) introduced the new art to a broader audience, and in 1980, 1983, and 1985 the the first three international ‘Fungi and fibre symposia’ were held in USA, Sweden and Denmark. In 1985 ‘The International Mushroom Dye Institute (IMDI)’ was founded, and today Dorothy Beebee coordinates the activities from her home in Forestville, California. Several textile artists in California have used mushroom dyes for tapestries and articles of clothing, e.g. Andreya Marks and Tigerlily Jones. At Mendocino Art Center the head of the textile department, Lolli Jacobsen, keeps the mushroom dye activities alive through courses and workshops. The dyeing agents of fungi is a fascinating matter which is still subject of further exploration. The mushroom dyes’ durability and fastness to light are better than most synthetic colours, and their chemical interaction with mordants (metallic salts) still offers unexpected colour possibilities.

SMF‘s gratulations and salutations - Swedish mycological Society - 52:13.

Mycomarathon – the first six months - Christian Lange & Thomas Læssøe - 52:14.
From January 1st to July 6th 39 persons have made 6564 records based on 1415 species in the Mycological society anniversary ‚mycomarathon‘. Many new country records have been made and many ‚early‘ occurrences have been noted.

The pyrenomycete genus Helminthosphaeria in Denmark - Thomas Læssøe & Jan Gert Borgergren Nielsen - 52:15-19.
The genus Helminthosphaeria (Sordariomycetidae, Ascomycota) is a relatively poorly known genus of mainly, possibly exclusively, fungicolous pyrenomycetes. Main hosts include the common clavarioid Clavulina cristata and some common corticioid fungi like Hyphoderma puberum. Four species are reported from Denmark, the well-known H. clavariorum and three new records for the country: H. corticiorum, H. hyphodermae and H. odontiae. All have few specimens in the national herbarium, but they are quite likely overlooked. H. hyphodermae occurred with its usual, but unconfirmed, anamorph (no name), whilst the others were associated with Diplococcium anamorphs.

Jørgen Mundt – member of the Danish Mycological Society for 70 years - Flemming Rune - 52:22-23.

Notes on rare fungi collected in Denmark - Thomas Læssøe (ed.) - 52:26-30.
A collection of Sirobasidium albidum, new to Denmark, is described from material on Eutypa on Acer?. The identification is based on the hyaline, white fructifications and the long chains of more or less globose basidia with a clamp seen at the base of the chain.
The first Danish records of Seticyphella niveola are presented with a collection on Crataegus leaves and one a Corylus? leaf. Both were collected in spring.
Aleurodiscis disciformis has been found for the first time in Denmark for more than 30 years. It was recorded from at least seven oak trees on two localities around Viborg in central Jutland.

The large mushroom festival - Flemming Rune & Ulrik Söchting - 53: 1-11.
To celebrate the centenary of the Danish Mycological Society on October 1st 2005 a five day mushroom festival was arranged in the Botanical Garden in central Copenhagen. A parade of more than 800 species of fresh macrofungi was the centre of a large exhibition giving a fascinating insight into the diverse world of fungi. Some 25 companies and research institutions demonstrated their work with fungi, and close to 1500 children and high school students were guided by university students. A large number of artists: painters, photographers, ceramicists, mushroom dyers, a wood turner and a mushroom totem pole sculptor displayed their work. Five notable Danish chefs, known from TV or as book authors, prepared 4000 cups of mushroom soup during the festival to the enjoyment of the public. The event was covered by TV, radio and newspapers, it had more than 11,500 visitors, and the society got 120 new members during the five days. The festival was arranged in cooperation between the society and University of Copenhagen.

Fungi and fibre symposium in Haslev - Susanne Thorbek & Preben Graae Sørensen - 53: 12-15.

The centenary of the Mycological Society of Bergen - Flemming Rune - 53: 18-20.
In May 1905 the 86-year-old army surgeon Christen Smith invited Norwegians to a meeting for establishing a mycological society in western and northern Norway. The first year the membership reached 111, but after Smith’s death in 1910, it decreased to only 18 in 1917. From 1917 to 1934 and from 1945 to 1954 there were almost no activities, but a grant founded by a generous patroness in 1908 helped resurrecting the society. The membership now is about 270, and the society arranges forays, courses, public mushroom identification, dyeing with mushrooms, and social evenings in the autumn.

New or rarely reported corticioid fungi from Denmark (Corticiaceae s.l., Thelephoraceae) - Jacob Heilmann-Clausen, Thomas Læssøe & Jan Vesterholt - 53: 21-32.
12 species of corticioid fungi (including Thelephorales), viz. Amylocorticium laceratum, Corticium erikssonii, Dendrothele citrisporella, Hyphoderma capitatum, Hyphodontia flavipora, Phlebia tristis, Phlebiella gaspesica, Pseudotomentella humicola, Sistotrema resinicystidium, Sistotrema raduloides, Tomentella clavigera and T. umbrinospora are reported as new to Denmark. In addition, the second Danish record of Amaurodon mustialaënsis is reported, and a more detailed account is given of the first Danish record of Sistotrema biggsiae. The latter species has previously been published from Denmark but without many details on the find, which is also the case for the Amaurodon. The reported species seem to be rare or very rare in Denmark, and indeed also in neighbouring countries, except Hyphodontia flavipora which is a rather frequent southern species in Europe spreading north, maybe as a result of global warming.

Serious decline for Danish grasslands - Jan Vesterholt & Bo Levesen - 53: 33-36.
The 188 most valuable grassland localities in Vejle County (E-Jutland) were surveyed in 2005 in order to get an overview of their present condition. The result was very disappointing. Only 81 localities (43%) were grazed, and 83 localities (44%) are in a more or less urgent need for resuming management. At present, grazing is subsidized by government/European Community means in 55 of the 81 grazed localities. Until 2004 it was possible to obtain subsidies in nearly all 188 localities, but now it will only be possible to apply for subsidies in Natura 2000 areas, and only 48 qualify as such. It is therefore expected that an increasing number of them will turn into shrub, leading to an accelerated decline for rare grassland species. Unfortunately, this trend seems to be nation wide.

Fungal names 2. Danish vernacular names for agarics - Poul Printz - 53: 42-46.

MycoMarathon 2005 – a status - Christian Lange - 53: 47-50.
A status of MycoMarathon, the online registration system of fungus records from Denmark is presented. 29,661 records of 2,840 species (including lichens) were entered by 55 collectors in 2005. The highest number of records from one collector was 4,555 and the highest number of species collected by one person was 1,386.
Some of the technical problems regarding the structure of the system are discussed and future plans presented. The registration system will continue under the name Svampefund („records of fungi“), on the adress: www.svampe.dk/svampefund.

Notes on rare fungi collected in Denmark - Jan Vesterholt (ed.) - 53: 55-60.
Obolarina dryophila is here recorded for the first time from Denmark after many years of searching in old oak stands. It was found in a very sun exposed site, where many rare and southern fungi occur, including Xerula pudens and Russula seperina. It is also reported from Blekinge (Sweden).
Dacrymyces ovisporus has been found for the first time in Denmark, on a Pinus branch near Silkeborg in Central Jutland.
The species Agaricus bohusii is reported for the first time from Denmark. It was first found on the Århus churchyard „Nordre Kirkegård“ in 1998, and has been seen in the area several times since then, forming fairy rings and breaking through the soil in clusters of closed caps with pointed scales. It seems very close to Agaricus subperonatus/vaporarius and is known from The Netherlands (Nauta 2001), England (Legon & Henrici 2005), Germany (Specht 2005) and southern and western Europe.
Lactarius zonarius has been found for the first time in Denmark in Eastern Jutland. Earlier reports of the species have been L. evosmus.

On the diffence between chanterelles and false chanterelles - Flemming Rune - 54: 1-8.
A selection of differences between chanterelles (Cantharellus/Craterellus) and false chanterelles (Hygrophoropsis) is presented. The intercalary growth of the initially smooth hymenium, the lack of a clearly defined subhymenial layer producing a palisade of simultaneously formed basidia, the elongated basidia exceeding 100 µm, and the meiotic spindle formed parallel to the longitudinal axis (stichobasidia) is outlined. The separation of Cantha­rellus and Craterellus is briefly described. The difference in taste and gastronomical value is discussed, and the author gives a few hints on preparation and preservation of chanterelles for gastronomers.

Tulostoma kotlabae new to Denmark - Mikael Jeppson - 54: 9-13.
Tulostoma kotlabae is reported as new to Denmark, and a key to the four Danish Tulostoma species (T. brumale, T. fimbriatum, T. kotlabae and T. melanocyclum) is provided. The new record of T. kotlabae was the result of a dedicated search for Tulostoma species in the sand dunes of NW Jutland in April 2005. However, a revision of the collections of Tulostoma at the Botanical Museum in Copenhagen (C) also revealed a previously misidentified record of this species from the same geographical area.

A fungus museum in northeast Germany - Henning Pedersen - 54: 18-21.
Impressions from a visit to a fungus museum in Darß-Fischland.

Notes on rare fungi collected in Denmark - Jan Vesterholt (ed.) - 54: 22-27.
Choiromyces meandriformis was found in a garden in Vejle, Jutland and ended up at the Society’s exhibition in the Copenhagen Botanical Garden.
Albatrellus syringae has been found for the first time in Denmark. It was rooting in soil on disturbed ground in an old gravel pit with Urtica dioica, Pinus nigra, Picea omorika, Salix caprea, Sambucus nigra and Betula in the northern part of Jutland. It seems unusual for the species that it was found as early as May 26.
Naucoria fellea is reported as new to Denmark based on two collections from Skagen, the northernmost tip of Denmark, where it was associated with Salix repens in dune slacks. Based on the available information we consider Alnicola cholea to be a younger synonym. Our material corresponds well with the interpretation in Ludwig (Pilzkompendium). In the field a striking likeness to Macrocystidia was noted.

New possibilities for mapping fungi - Christian Lange & Else Østergaard Andersen - 54: 28-34.
Maps with dots representing data on species occurrence are highly useful in biological diversity projects. Such maps are typically produced on a rather local scale, typically a country. Now the GBIF secretariat (Global Biodiversity Information Facility, www.gbif.org) and its local counterparts, the national nodes, are progressing fast in creating an international web based search system. This system is capable of showing maps of records of all kinds of organisms on a worldwide scale, using the mapping techniques created by Google (www.GoogleEarth.com). Examples of such maps using this system are presented, using Cantharellus cibarius. The need for more data and a precise geo-reference to enhance the quality of the occurRence maps is emphasized.

Three effused and very similar Hypoxylon species - Thomas Læssøe - 54: 35-40.
Three macroscopically rather similar Hypoxylon species are briefly described and discussed. Hypoxylon macro­carpum is mainly found on big, decorticated, very hard wooded trunks (e.g. Fagus and Ulmus) but has a very wide host range and may occasionally grow on bark, whilst H. petriniae typically occurs on corticated Fraxinus. Hypoxylon rubiginosum has a broad host range and occurs on both corticated and decorticated wood. The true frequencies of these conspicuous stromatic pyrenomycetes cannot be stated at present, but they would all appear to be common over most of Denmark. The preference for large trunks makes H. macrocarpum a better candidate as an indicator species for valuable woodland than the other two. An annotated list of further species of Hypoxylon not yet recorded from Denmark, but considered possible, is given at the end.

Ovulinia azaleae, the cause of petal blight of Rhododendron, in Denmark - Jørgen Koch & Iben M. Thomsen - 54: 41-48.
Ovulinia azaleae was identified in Denmark in 2002. Seriously attacked in 2004 were Rhododendron catawbiense ‘Gomer Waterer’, Rh. catawbiense x(?) and Rh. nakaharae. The disease was less serious on Rh. ponticum x ‘Roseum’ and Rh. catawbiense x ‘Fastuosum Flore Pleno’. Furthermore, in 2006 attacks were observed in Rh. calendulaceum, Rh. catawbiense, Rh. luteum, Rh. catawbiense x ‘Lee’s Dark Purple’ and ‘Purple Splendour’, Rh. occidentale x ‘Irene Koster’, Rh. molle ssp. japonicum x ‘Brilliant Red’ and ‘Persil’ (Knaphill hybrid) and other hybrids. Under garden conditions apothecia were obtained after 1 and 2 years, ripening from mid April to June 1st. Apothecia with a slender trumpet formed stalk up to 9 mm long, disc 3 mm across, outside with a layer up to 140 mm thick of thin-walled, isodiametric cells 12-36 µm in diameter. Ascospores measured from spore cast: 12-15.4-19 x 7-7.7-11 µm. Conidia formed under dry conditions: 26-30.6-36 x 18-20.6-24 µm, under wet conditions: 28-36.4-49 x 12-15.4-18 µm. Hyphae in corolla tissue of two types: 1) thin-walled, 4-6 µm wide, producing conidia; and 2) uneven, thick-walled, up to 20 µm wide (vessel like), often forming small, flat ribbons in the tissue. Material will be deposited in the Herbaria CP and C, Copenhagen.

Little Sweden - Thomas Læssøe & Jan Gert Borgergren Nielsen - 55: 11-23.
A partly drained boggy forest, originally planted with spruce more than one hundred years ago, has been left unmanaged. It now contains many decay classes of dead trunks, mainly from spruce and birch, and spruce is regenerating. The forest contains many small ponds created by uprooted spruce and the relative humidity is generally very high. Dominant fungi on spruce include Fomitopsis pinicola, Trichaptum abietinum, Exidia pithya and much more surprising Pycnoporellus fulgens. National rarities are Exidia cartilaginea, Climacocystis borealis, Psilocybe turficola, Phellinus lundellii (first DK record) and others. Even an undescribed fungus, a species of Neobarya, was uncovered on rotten Picea bark.

Notes on rare fungi collected in Denmark - Jan Vesterholt (ed.) - 55: 24-38.
Aurantioporus croceus is recorded high up on a big standing oak, very close to the only known, now strongly decayed trunk, from where this species has been recorded in recent times.
The boreal polypore Phellinus lundellii is surprisingly recorded as being Danish from an area locally known as “Little Sweden”. This area also boasts other mainly boreal polypores.
Artomyces pyxidatus is recorded as new to Denmark. It was found in a protected site in Northern Jutland, on a moss covered trunk of Populus tremula.
Resupinatus taxi (Stigmatolemma taxi) has been recorded for the first time in Denmark, on a twig of Juniperus communis. The host and the pseudoangular spores are diagnostic.
Lyophyllum aemiliae, recently described from Italy, was found in an Abies dominated plantation on calcareous sand. Its remarkable feature is that the gills stain orange when bruised.
Lyophyllum osmophorum is with some hesitation reported as Danish. The material is less omphaloid compared to the original description, but the smell, recalling Inocybe bongardii, is in accordance, unlike the record in Ludwig’s Pilzkompendium. The microscopical details more or less agree with the description in Gilbert.
Rhodotus palmatus, known from all neighbouring countries, has now been found in Denmark, in Eastern Jutland on a fallen trunk of Fagus.
Porpoloma spinulosum can now be removed from the extinct category based on two finds in 2006, one under old oaks and the other in a more mixed broad-leaved forest. Both sites are rich in rare fungi and the soil is alkaline. Earlier records were from 1932, 1938 and 1953.
The status of Lepiota subgracilis in Denmark is reviewed in the light of two finds from 2006. Previously it was known from four localities (now six). It is typically not associated with Lepiota hotspots although it has been recorded at least once in such a spot.
Panaeolus guttulatus is recorded as new to Denmark, with finds from the islands Sjælland and Møn. Three collections were made in more or less disturbed and open areas in deciduous forests on calcareous soil.

Suillus placidus – an immigrant under white pines in Denmark - Flemming Rune - 56: 1-5.
Suillus placidus has been recorded less than 10 times under 5-needle pines in Denmark since 1913. The author describes a recent find of several hundred fruitbodies, and discusses the distribution of the species. The primary host in Denmark is introduced Eastern White Pine (Pinus strobus), but since the 1860’s all silviculture of that species has been abandoned due to blister rust (Cronartiun ribicola). Thus, Suillus placidus is still a very rare species in Denmark, included in the Danish red list of rare and endangered species.

The fungus forecast? - Erik Rald - 56: 16-19.
The reader is advised to keep an eye on the meteorologists‚ nation-wide drought index. The soil moisture is calculated on a daily basis and displayed at the website of the Danish Meteorological Institute, www.dmi.dk/dmi/index/danmark/torkeindex.htm. The areas with the largest amount of soil moisture are the ones most likely to produce a good mushroom crop sometime in the future.

Late May field meeting with 24 new Danish ascomycetes - Thomas Læssøe & Jens H. Petersen - 56: 21-28.
A dedicated group of European ascomycetologists in late May 2007 joined a workshop held at the field centre Kristiansminde, Sjælland, Denmark. Although much work remains to be done on the collections we can report the following taxa as new to Denmark, some more surprising than others: (discomycetes) Calycellina ochracea, Cenangiopsis quercicola, Cistella aconiti, Hyphodiscus theiodeus, „Laetinaevia“ uvidula (Pezizella uvidula), Orbilia dryadum, O. euonymi, O. rectispora, Pseudopeltis filicinum and Rodwayella citrinula; (other ascomycetes) Acanthostigmella orthoseta, Arnium apiculatum, Byssothecium flumineum, Ceratostomella rostrata, Cryptodiaporthe hystrix, Diaporthe decedens, D. varians, Jahnula aquatica, Massarina corticola, Massariosphaeria typhicola, Phomatospora moravica, Trematosphaeria hydrophila, Trematosphaeria wegeliniana and Ascitendus austriacus; (basidiomycetes) Galerina cinctula; (hyphomycetes) Asterosporium asterospermum.

The genus Parasola in Denmark - Jan Vesterholt, Erik Rald & Thomas Læssøe - 56: 29-37.
The genus Parasola is considered as separate from Coprinus, and a survey and key is given to the 10 species known from Denmark. P. lilatincta is reported as new to Denmark.

Cortinarius vesterholtii - Tobias Guldberg Frøslev - 56: 38-42.
The history behind the recent publication of Cortinarius vesterholtii is given. The species is named in honour of Jan Vesterholt. The species has formerly been treated as C. provencalis, which however is a later synonym for C. sodagnitus.

Interesting species of Cortinarius subgenus Phlegmacium from broadleaved forest in Scandinavia - Tobias G. Frøslev & Thomas S. Jeppesen - 56: 43-56.
Ten rare and interesting species of Cortinarius subgenus Phlegmacium are presented and discussed. C. cliduchus and C. obsoletus are presented as new to Denmark and Northern Europe. C. gracilior, C. xanthochlorus and C. viridocoeruleus are presented as new to Denmark. C. prasinocyaneus is presented, and C. moënne-loccozii is presented for the first time under this name, although it has been recorded from Sweden for some time. C. subhygrophanus, C. rapaceotomentosus and C. xanthosuavis are presented as new to Sweden and Northern Europe.

Notes on rare fungi collected in Denmark - Jan Vesterholt (ed.) - 56: 57-62.
Tricholoma batschii was found in a cemetery in Herlev, Copenhagen, in association with Pinus nigra. It is the first verified Danish record of the species.
Three species of Cortinarius, subgenus Telamonia, are reported as new to the Danish funga. C. alborufescens Imler characterized by abundant cream-coloured veil and small, narrow spores was found in two sandy localities with Pinus and Betula. In one of these localities, also C. venustus P. Karst. was found, a species recognized by pale violet veil and stem and a fruity smell recalling C. traganus. The third species, C. fragrantior Gaugué, was found in a calcareous deciduous forest with Fagus and Quercus. It is characterized by a date brown cap, whitish, somewhat rooting stem, distant gills and roundish spores.

These strange men - Poul Printz - 57: 14-15.

New truffle records - Flemming Rune - 57: 16-17.
In 2007, for the fifth year running, giant Piedmont (white) Truffles (Tuber magnatum) from Italy were sold at world record prices. The third largest truffle ever found, a 1497 g monstrosity, brought in US$ 330,000 at an auction in Macau on December 1st. Mrs Angela Leong made the winning bid for her husband, billionaire Stanley Ho, a Macau casino mogul. The lucky truffle hunter Cristiano Savini, whose mongrel dog Rocco found the truffle one week earlier at Palaia in Tuscany 35 km SE of Pisa, donated the amount to charity.

The genus Melanoleuca in Denmark - Jan Vesterholt - 57: 18-29.
A survey and key is given to 14 species of Melanoleuca of which 13 are recognized from Denmark. M. atripes and M. microcephala are reported as new to the Danish funga.

Notes on rare fungi collected in Denmark - 57: 30-37.
Camarops pugillus is for the first time reported from Denmark, and in addition as new to southern Sweden (Skåne). It was found on a fallen Corylus branch on top of big beach stones near the sea in southeastern Denmark.
Lyophyllum hebelomoides is reported from an area, that apparently resembles the Berlin-Spandau type locality: sunny, sandy place with Populus. A more fasciculate habit was noted compared to the type description. The colours are in accordance with those reported by Ludwig (2001) or slightly darker, rather than those from the type description. Ludwig’s observations were made on the living type material. In the field the strange dirty grey brown, crowded lamellae stand out, but generally speaking this is a very dull grey brown job. Exsiccatae become sooty grey (esp. the gills) as in the staining Lyophyllum species.
Marasmius collinus was found for the first time in Denmark, among grass and low herbs in an open track in an Abies dominated forest on calcareous sand.
Entoloma jahnii is reported as new to Denmark from northern Jutland - on a rotten Quercus branch.
Leucoagaricus sublittoralis is likewise recorded as new to Denmark, based on material from three localities of a rather varied nature: in a coastal dune area situated on the island Lolland, southeastern Denmark, in an ancient mixed, unmanaged deciduous woodland (Zealand) and in a mixed hedge on Funen Island. All collections have broad hyphae in the epicutis.
