| Based on type studies and freshly collected material we here re-instate the genus Thyronectria (Nectriaceae, Hypocreales). Species of this genus were recently for the most part classified in the genera Pleonectria (Nectriaceae) or Mattirolia (Thyridiaceae), because Thyronectria and other genera had been identified as members of the Thyridiaceae due to the presence of paraphyses. Molecular phylogenies based on several markers (act, ITS, LSU rDNA, rpb1, rpb2, tef1, tub) revealed that the Nectriaceae contain members whose ascomata are characterised by long, more or less persistent, apical paraphyses. All of these belong to a single genus, Thyronectria, which thus has representatives with hyaline, rosy, green or even dark brown and sometimes distoseptate... |
