Anamorphic chaetosphaeriaceous fungi exhibit high morphological variability and are distributed worldwide across terrestrial aquatic habitats. During an ongoing taxonomic study of microfungi, two intriguing hyphomycetes were collected from dead wood bamboo stems in China Thailand. A polyphasic approach, combining characteristics phylogenetic analysis LSU ITS sequence data, revealed that these represent new genera within Chaetosphaeriaceae. Pseudolomaantha Submultiguttulispora proposed for genera, they non-phialidic phialidic asexual morphs, respectively. Pseudolomaanthathailandica gen. et sp. nov. is characterized by a sporidesmium-like morph with macronematous, mononematous conidiophores; monoblastic conidiogenous cells, pyriform to obclavate, rostrate conidia bearing apical appendage. Submultiguttulisporamultiseptata distinguished conidiophores, mono- polyphialidic fusiform or ellipsoidal-fusiform, pale brown olive green filiform, hyaline appendages at both ends.
