Molecular phylogenies using 1-4 gene regions and information on ecology, morphology and pigment chemistry were used in a partial revision of the agaric family Hygro- phoraceae. The phylogenetically supported genera we recognize here in the Hygrophoraceae based on these and previous analyses are: Acantholichen, Ampulloclitocybe, Arrhenia, Cantharellula, Cantharocybe, Chromosera, Chrysomphalina, Cora, Corella, Cuphophyllus, Cyphellostereum, Dictyonema, Eonema, Gliophorus, Haasiella, Humidicutis, Hygroaster, Hygrocybe, Hygrophorus, Lichenomphalia, Neohygrocybe, Porpolomopsis and Pseudoarmillariella. A new genus that is sister to Chromosera is described as Gloioxanthomyces. Revisions were made at the ranks of subfamily, tribe, genus, subgenus, section and subsection. We present three new subfamilies, eight tribes (five new), eight subgenera (one new, one new combination and one stat. Nov.), 26 sections (five new and three new combinations and two stat. Nov.) and 14 subsections (two new, two stat. Nov.). Species of Chromosera, Gliophorus, Humidicutis, and Neohygrocybe are often treated within the genus Hygrocybe; we therefore provide valid names in both classification systems. We used a minimalist approach in transferring genera and creating new names and combinations. Consequently, we retain in the Hygrophoraceae the basal cuphophylloid grade comprising the genera Cuphophyllus, Ampulloclitocybe and Cantharocybe, despite weak phylogenetic support. We include Aeruginospora and Semiomphalina in Hygrophoraceae based on morphology though molecular data are lacking. The lower hygrophoroid clade is basal to Hygrophoraceae s.s., comprising the genera Aphroditeola, Macrotyphula, Phyllotopsis, Pleurocybella, Sarcomyxa, Tricholomopsis and Typhula. © 2013 The Author(s).

Formal proposals to conserve or protect fungal names as well as proposals to amend the INTERNATIONAL CODE OF NOMENCLATURE of immediate interest to mycologists are now published concurrently in MYCOTAXON and TAXON. Conservation proposals include Prop. 1918 (to conserve the name Dermatocarpon bucekii against Placidium steineri), Prop. 1919 (to conserve the name Lactarius with a conserved type), Prop. 1926 (to conserve the name Cladia against Heterodea, and Prop. 1927 (to conserve the name Agaricus rachodes with that spelling). Props. 117-119 to amend the CODE ask for pre-publication deposit of nomenclatural information in a recognized repository for valid publication of fungal names. Source

Authors (including some of us) have incorrectly cited as basionyms names treated by Fries in 1863 that were actually originally published by him in 1861. As these basionym citation errors mean that the intended new combinations are not validly published, the following combinations are again proposed as new: Chromosera cyanophylla, Mythicomyces corneipes, Tephrocybe misera, T. tesquorum. Three other intended combinations are noted as also not validly published, but the species are currently treated under the different (and validly published) names Haasiella venustissima, Phaeoclavulina curta, and Rhodonia placenta. © 2011.

A species of Inocybe common in Washington, Oregon and British Columbia is documented and described as new. The species, I. chondroderma, is characterized by these features: pileus with a fulvous disk and ochraceous to chamois margin, presence of a cortina, densely mycelioid stipe base, smooth spores and fall phenology. The most reliable and distinctive feature of the species is a blue-green or turquoise reaction in response to application of a solution of pdimethylaminobenzaldehyde (PDAB), indicating the presence of what is most likely an indole alkaloid. PDAB use provides a quick and diagnostic character easily implemented in a laboratory setting. ITS sequences from recent collections of I. chondroderma and from materials collected in the 1940s in Washington and Oregon fully match numerous mislabeled sequences from specimens in British Columbia and Oregon. The species is most closely related to an unclarified taxon from Colorado and Japan (I. cf. chondroderma) and a rare European species, I. subnudipes. Nine different species names in Inocybe and one in Hebeloma attributed to I. chondroderma based on GenBank BLASTN searches of the ITS locus match with 99-100% similarity, reinforcing concerns about taxonomic inaccuracies in public DNA sequence databases. A complete morphological description, illustrations and phylogenetic assessment are provided. © 2013 by The Mycological Society of America. Source
