摘 要:Specimens regarded as Thelonectria discophora(Thelonectria,Nectriaceae,Hypocreales)constitute a conspicuous group of saprobic fungi on decaying plant material,characterized by red perithecia each with a broad mammiform(nipple-like)*** asexual state is characterized by a cylindrocarpon-like morphology,with 3–5 septate macroconidia,unicellular microconidia and chlamydospores that are rarely produced in *** the past,*** was regarded as one species with a wide geographic ***,a recent study rejected the monophyly and cosmopolitan distribution of this species,and showed the existence of at least 16 cryptic species distributed in three main *** combining the results of phylogenetic analyses of six nuclear loci and morphological studies,we revised the taxonomy of the *** species complex,resulting in the description of 12 new species and four new combinations based on historic *** though molecular phylogenetic analyses strongly support the segregation of these species,and are in agreement with previous studies,individual diagnostic morphological characters for each species could not be ***,discrete morphological traits corresponding to each of the three main groups of species were *** could be differentiated based on the average values of morphological traits as well as the presence/absence of characteristic asexual propagules and colony growth at ***,illustrations are provided for the recognized species.
