Morpho-phylogenetic evidence reveals Pseudolomaanthathailandica gen. et sp. nov. and Submultiguttulisporamultiseptata gen. et sp. nov. in Chaetosphaeriaceae.

ABSTRACT: Anamorphic chaetosphaeriaceous fungi exhibit high morphological variability and are distributed worldwide across terrestrial and aquatic habitats. During an ongoing taxonomic study of microfungi, two intriguing chaetosphaeriaceous hyphomycetes were collected from dead wood and dead bamboo stems in China and Thailand. A polyphasic approach, combining morphological characteristics and phylogenetic analysis of LSU and ITS sequence data, revealed that these fungi represent two new genera within Chaetosphaeriaceae. Pseudolomaantha and Submultiguttulispora are proposed for these new genera, and they exhibit non-phialidic and phialidic asexual morphs, respectively. Pseudolomaanthathailandica gen. et sp. nov. is characterized by a sporidesmium-like asexual morph with ma
