Genus Cortinarius, subgenus Phlegmacium in Tasmania

Abstract

There has been no comprehensive work accounting for a hierarchical position of Phlegmacium world-wide since 1986. The advent of molecular research, however, has given new insights on the relationships among the species of this subgenus. I have studied a number of species from Tasmania and assign them to infrageneric taxa that recognise these new relationships and encompass a wide range of species in all geographical regions. The descriptions of 40 species of Cortinarius, subgenus Phlegmacium are provided including 27 new species (C. australis, C. austrocausticus, C. austrosaginus, C. austrovaginatus, C. caeruleoëburneus, C. cap-sicosmus, C. chrysopocos, C. chrysochalybdeus, C. coelopus, C. elatostipitatus, C.fucatus, C. fulvoiubatus, C. ingratolens, C. lacteus, C. madidus, C. memoria-annae, C. nijerrus, C. phaeouranus, C. pseudoporphyropus, C quaresimalis, C. rubescens, C. salmaster, C. sclerophyllarum, C. submeleagris, C. subsciorophyllus, C. ulematus, and C. wirrabara) and one variety (C. austrocyanites var. brunyiensis). The following supraspecific taxa are proposed, validated, or described as new: 1 Section (Rotundo-sporati), 4 Subsections (Coelopodati, Myxacioidei, Rozites, Subpolitosporei), 10 new Series (Archeriani, Australiensium, Austroalbidi, Barbati, Chrysochroi, Inflatipedes, Mariae, Perizoniati, Pudorini, and Xiphidipodes), and 2 new subseries, Volvatus and Sinapicolores. C. lavendocaeruleus is here lectotypi-fied. Section Archeriani and Subsection Malvacei are transferred from subgenus Myxacium to subgenus Phlegmacium. © 2007 Taylor & Francis Group, LLC.
