| 1 | Molecular phylogeny, morphology, pigment chemistry and ecology in Hygrophoraceae (Agaricales)显示文摘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 Hygrophoraceae.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 andCantharocybe,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. | D.Jean Lodge Mahajabeen Padamsee P.Brandon Matheny M.Catherine Aime Sharon A.Cantrell David Boertmann Alexander Kovalenko Alfredo Vizzini Bryn T.M.Dentinger Paul M.Kirk A.Martyn Ainsworth Jean-Marc Moncalvo Rytas Vilgalys Ellen Larsson Robert Lücking Gareth W.Griffith Matthew E.Smith Lorelei L.Norvell Dennis E.Desjardin Scott A.Redhead Clark L.Ovrebo Edgar B.Lickey Enrico Ercole Karen W.Hughes Régis Courtecuisse Anthony Young Manfred Binder Andrew M.Minnis Daniel L.Lindner Beatriz Ortiz-Santana John Haight Thomas Læssøe Timothy J.Baroni József Geml Tsutomu Hattori | 2014 | Fungal Diversity2014，，1： | 0 |
| 2 | Taxonomy of Pseudolagarobasidium(Polyporales,Basidiomycota)显示文摘Pseudolagarobasidium(Polyporales,Basidiomycota)is a small,monophyletic genus of crustose,wood-inhabiting fungi with spines and a saprobic,endophytic,or parasitic habit.Seven species are accepted in the genus including two new species,P.belizense from Belize and P.pusillum from Australia.Sequence analysis of the internal transcribed spacer of the ribosomal RNA gene places P.belizense in a monophyletic clade with P.acaciicola and an undescribed foliar endophyte.New combinations proposed include P.modestum for Irpex modestus Berk.,P.pronum for Hydnum pronum Berk.&Broome which is an earlier name for P.calcareum,and P.venustum for Radulodon venustus Hjortstam&Ryvarden.Irpex colliculosum Berk.&Broome from Sri Lanka is conspecific with P.subvinosum.Two species,Sistotrema ochroleucum and Radulum concentricum are not accepted in Pseudolagarobasidium.Pseudolagarobasidium is compared with Radulodon and similar genera.A key to the species of Pseudolagarobasidium is provided. | Karen K.Nakasone Daniel L.Lindner | 2012 | Fungal Diversity2012，，4： | 0 |
