Multi-locus phylogeny reveals two new species ofExidia(Auriculariales,Basidiomycota) from China

Exidia glandulosais a cosmopolitan species, and it was commonly reported from China. Seventeen specimens with close resemblance to the species by having blackish, gelatinous basidiocarps were analyzed based on morphological and molecular data. Phylogenetic analyses were performed by the combined ITS+nLSU dataset and the combined ITS+nLSU+TEF1-a + RPB2dataset, and 20 ITS, 20 nLSU, 22TEF1-a, and 20RPB2sequences were newly generated. Seventeen specimens were gathered into three different lineages in phylogenies, and they were identified as three species,E. glandulosas. str. and two new species,E. reflexaandE. subglandulosa, respectively. The two new species differ fromE. glandulosas. str. by the absence of papillae on hymenial surface, andE. reflexadiffers fromE. subglandulosaby obvious effused-reflexed basidiocarps and smaller basidia and basidiospores. Detailed characteristics with morphological photos of two new species were provided here.
