Abstract

While investigating culturable mycobiota in epiphytic soils found in urban tree holes from Guizhou Province, China, a new genus along with two new species of the family Wiesneriomycetaceae were discovered based on a combination of morphological characteristics, molecular evidence, and physiological features. Phylogenetic analyses of SSU, ITS, LSU, and tef1 sequences indicate that our new collections form a distinct clade; thus, Chlamydosporoidesgen. nov. is proposed. This genus is distinguished from other genera in Wiesneriomycetaceae by the absence of acropetal conidial chains, setae, synnemata, sporodochia, or stromata. We describe and illustrate the new genus Chlamydosporoides and the new species (C. guizhouensissp. nov. and C. sinensissp. nov.) herein, and we discuss their phenotypic and genotypic differences from allied genera.
