Abstract

During an investigation of lignicolous freshwater fungi in the Tibetan Plateau, three Aquapteridospora taxa were collected from freshwater habitats in Xizang, China. The new species possess polyblastic, sympodial, denticles conidiogenous cells and fusiform, septate, with or without sheath conidial, that fit within the generic concept of Aquapteridospora, and multi-gene phylogeny placed these species within Aquapteridospora. Detailed morphological observations clearly demarcate three of these from extant species and are hence described as new taxa. The multi-gene phylogeny of the combined LSU, TEF1-α, and ITS sequence data to infer phylogenetic relationships and discuss phylogenetic affinities with morphologically similar species. Based on morphological characteristics and phylogenetic analyses, three new species viz. A. linzhiensis, A. yadongensis, and A. submersa are introduced. Details of asexual morphs are described, and justifications for establishing these new species are also provided in this study.
