| 1 | Pseudoclitocybaceae fam. nov. (Agaricales, Tricholomatineae), a new arrangement at family, genus and species level显示文摘A new classification of several clitocyboid taxa is here proposed to accommodate results from multigenic phylogenetic inference.The analysis of ITS rDNA as well as a combined dataset including 18S and 28S rDNA,tef1 and rpb2 data,support significantly a shared monophyletic origin of the genera Pseudoclitocybe,Musumecia and Pogonoloma,and the species Clitocybe alexandri and C.harperi.The new family Pseudoclitocybaceae is here proposed to name this clade,characterized by the presence of loop-like clamp connections in most species,absence of cystidia,and parallel hymenophoral trama with broad,cylindrical hyphae with intracellular granulations.The new genera Clitopaxillus and Harmajaea are proposed to accommodate the type species C.alexandri and H.harperi,as well as the combination H.wellsiae.In addition,two new species are described:C.fibulatus has a differential distribution of clamp connections in the basidiome,while H.guldeniae is,by now,an exclusively European taxon with brownish pileus,somewhat decurrent gills,ovoid spores and basidia longer than those of H.harperi.Finally,the species concept within Pseudoclitocybe and Pogonoloma is discussed and descriptions of the most representative species are provided. | Pablo Alvarado Pierre-Arthur Moreau Balint Dima Alfredo Vizzini Giovanni Consiglio Gabriel Moreno Ledo Setti Tapio Kekki Seppo Huhtinen Kare Liimatainen Tuula Niskanen | 2018 | Fungal Diversity2018，，3： | 2 |
| 2 | Notes,outline and divergence times of Basidiomycota显示文摘The Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota.The present work provides an overview of all validly published,currently used basidiomycete genera to date in a single document.An outline of all genera of Basidiomycota is provided,which includes 1928 currently used genera names,with 1263 synonyms,which are distributed in 241 families,68 orders,18 classes and four subphyla.We provide brief notes for each accepted genus including information on classification,number of accepted species,type species,life mode,habitat,distribution,and sequence information.Furthermore,three phylogenetic analyses with combined LSU,SSU,5.8s,rpb1,rpb2,and ef1 datasets for the subphyla Agaricomycotina,Pucciniomycotina and Ustilaginomycotina are conducted,respectively.Divergence time estimates are provided to the family level with 632 species from 62 orders,168 families and 605 genera.Our study indicates that the divergence times of the subphyla in Basidiomycota are 406-430 Mya,classes are 211-383 Mya,and orders are 99-323 Mya,which are largely consistent with previous studies.In this study,all phylogenetically supported families were dated,with the families of Agaricomycotina diverging from 27-178 Mya,Pucciniomycotina from 85-222 Mya,and Ustilaginomycotina from 79-177 Mya.Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system,and also provide a better understanding of their phylogeny and evolution. | Mao-Qiang He Rui-Lin Zhao Kevin D.Hyde Dominik Begerow Martin Kemler Andrey Yurkov Eric H.C.McKenzie Olivier Raspe Makoto Kakishima Santiago Sanchez-Ramırez Else C.Vellinga Roy Halling Viktor Papp Ivan V.Zmitrovich Bart Buyck Damien Ertz Nalin N.Wijayawardene Bao-Kai Cui Nathan Schoutteten Xin-Zhan Liu Tai-Hui Li Yi-Jian Yao Xin-Yu Zhu An-Qi Liu Guo-Jie Li Ming-Zhe Zhang Zhi-Lin Ling Bin Cao Vladimir Antonin Teun Boekhout Bianca Denise Barbosa da Silva Eske De Crop Cony Decock Balint Dima Arun Kumar Dutta Jack W.Fell Jozsef Geml Masoomeh Ghobad-Nejhad Admir J.Giachini Tatiana B.Gibertoni Sergio P.Gorjon Danny Haelewaters Shuang-Hui He Brendan P.Hodkinson Egon Horak Tamotsu Hoshino Alfredo Justo Young Woon Lim Nelson Menolli Jr Armin Mesic Jean-Marc Moncalvo Gregory M.Mueller La szlo G.Nagy RHenrik Nilsson Machiel Noordeloos Jorinde Nuytinck Takamichi Orihara Cheewangkoon Ratchadawan Mario Rajchenberg Alexandre G.S.Silva-Filho Marcelo Aloisio Sulzbacher Zdenko Tkalcec Ricardo Valenzuela Annemieke Verbeken Alfredo Vizzini Felipe Wartchow Tie-Zheng Wei Michael WeiB Chang-Lin Zhao Paul M.Kirk | 2019 | Fungal Diversity2019，，6： | 0 |
