The stipitate hydnoid fungus Hydnellum cumulatum, originally described from Canada, is re- ported as new to Sweden. It was collected in 2007 in two old stands of Picea abies (Tuskö- sundet and Plogmyren) in the coastal region of eastern-central Sweden in the province of Uppland near Östhammar. The species had been found there before and provisionally identified as Hydnellum scrobiculatum. Two other Swedish herbarium collections under the latter name also proved to belong to H. cumulatum. A full description in Swedish and English of that species is provided. The differences between H. scrobiculatum and H. concrescens are discussed. Spore size and ornamentation are the most important discriminating characters, but they are probably also recognisable in the field on differences in pileus surface and smell. More research is needed to confirm this. The conspecifity between European and American collections of H. cumulatum is discussed. The identity of H. scrobiculatum and its occurrence in Sweden are discussed as well. It is concluded that this taxon may be a phantom species, falling within the variation of H. concrescens, but more research is needed including a renewed study of the neotype collected near Femsjö, Sweden.

We report here the results of an inventory of basidiomycetes, which was undertaken in the region of Nafpactia Mts., central Greece. The investigated area, with woods dominated by C. sativa, was examined for the first time in respect to its mycodiversity. One hundred and four species belonging in 54 genera were recorded. Fifteen species (Conocybe pseudocrispa, Entoloma nitens, Lactarius glaucescens, Lichenomphalia velutina, Parasola schroeteri, Pholiotina coprophila, Russula alutacea, R. azurea, R. pseudoaeruginea, R. pungens, R. vitellina, Sarcodon glaucopus, Tomentella badia, T. fibrosa and Tubulicrinis sororius) are reported for the first time from Greece. In addition, 33 species constitute new habitats/hosts/substrates records. Key words — biodiversity, macromycete, Mediterranean, mushroom Introduction Castanea sativa Mill., Fagaceae (sweet chestnut) generally prefers north- facing slopes where the rainfall is greater than 600 mm, on moderately acid soils (pH 4.5–6.5) with a light texture.

And what of rumors that we have the “true” matsutake of Asia in parts of North America? Whether you call it pine mushroom or matsutake (or simply the more affectionate nickname “matsi”), there can be no question that this mushroom is one of the most highly prized in the world. It can be an acquired taste to Westerners (I personally love them!); among Japanese this mushroom is king, with prices for top specimens fetching kings’ ransoms. Annually, Japanese matsutake mavens will spend US$50-100 for a single top quality specimen and prices many times this are regularly reported. Because the demand far f you reside in Canada you likely call exceeds the supply in Japan (97% of them pine mushrooms; in the USA, matsutake mushrooms consumed in most refer to them by their Japanese Japan, annually, are imported, according Iname, matsutake.

Burdsall, Jr. Synopsis Fungorum 8 Fungiflora - Oslo - Norway 6 Authors address: Center for Forest Mycology Research Forest Products Laboratory United States Department of Agriculture Forest Service One Gifford Pinchot Dr. Madison, WI 53705 USA ABSTRACT Once a taxonomic refugium for nearly any white-spored agaric with an annulus and attached gills, the concept of the genus Armillaria has been clarified with the neotypification of Armillaria mellea (Vahl:Fr.) Kummer and its acceptance as type species of Armillaria (Fr.:Fr.) Staude. Due to recognition of different type species over the years and an extremely variable generic concept, at least 274 species and varieties have been placed in Armillaria (or in Armillariella Karst., its obligate synonym). Only about forty species belong in the genus Armillaria sensu stricto, while the rest can be placed in forty-three other modem genera. This study is based on original descriptions in the literature, as well as studies of type specimens and generic and species concepts by other authors. This publication consists of an alphabetical listing of all epithets used in Armillaria or Armillariella, with their basionyms, currently accepted names, and other obligate and facultative synonyms.

La documentazione, circa la loro presenza, viene dedotta dai resti fossili venuti recente- mente alla luce, risalenti a moltissimi milioni di anni fa: nei resti del carbonifero (300 milioni di anni fa) sono, infatti, riconoscibili varietà di funghi ancora oggi presenti tra le specie della flora fungina. Le popolazioni primordiali, agli inizi della civiltà umana, hanno avuto sicuramente di- mestichezza con i funghi, sia per scopi alimentari che per pratiche religiose ed arti- stiche. Oggi non siamo a conoscenza del significato che i funghi rappresentavano per l‟uomo primitivo. Non è noto, infatti, se egli se ne nutrisse o se li ignorasse, né tanto- meno se fosse in grado di distinguere le specie eduli da quelle velenose. Tra gli oggetti ritrovati nello zaino dell‟uomo di Similaun, risalente a più di 5000 anni fa, vi erano anche funghi allucinogeni secchi.

  • A Preliminary Checklist of Arizona Macrofungi
    A PRELIMINARY CHECKLIST OF ARIZONA MACROFUNGI Scott T. Bates School of Life Sciences Arizona State University PO Box 874601 Tempe, AZ 85287-4601 ABSTRACT A checklist of 1290 species of nonlichenized ascomycetaceous, basidiomycetaceous, and zygomycetaceous macrofungi is presented for the state of Arizona. The checklist was compiled from records of Arizona fungi in scientific publications or herbarium databases. Additional records were obtained from a physical search of herbarium specimens in the University of Arizona’s Robert L. Gilbertson Mycological Herbarium and of the author’s personal herbarium. This publication represents the first comprehensive checklist of macrofungi for Arizona. In all probability, the checklist is far from complete as new species await discovery and some of the species listed are in need of taxonomic revision. The data presented here serve as a baseline for future studies related to fungal biodiversity in Arizona and can contribute to state or national inventories of biota. INTRODUCTION Arizona is a state noted for the diversity of its biotic communities (Brown 1994). Boreal forests found at high altitudes, the ‘Sky Islands’ prevalent in the southern parts of the state, and ponderosa pine (Pinus ponderosa P.& C. Lawson) forests that are widespread in Arizona, all provide rich habitats that sustain numerous species of macrofungi. Even xeric biomes, such as desertscrub and semidesert- grasslands, support a unique mycota, which include rare species such as Itajahya galericulata A. Møller (Long & Stouffer 1943b, Fig. 2c). Although checklists for some groups of fungi present in the state have been published previously (e.g., Gilbertson & Budington 1970, Gilbertson et al. 1974, Gilbertson & Bigelow 1998, Fogel & States 2002), this checklist represents the first comprehensive listing of all macrofungi in the kingdom Eumycota (Fungi) that are known from Arizona.
