摘要： Two novel species within the family Dictyosporiaceae are described and illustrated from terrestrial habitats on dead culms of bamboo and an unidentified plant, respectively. Through morphological comparisons and the multi-locus phylogenetic analyses of combined LSU, ITS, SSU, and tef1-alpha sequence dataset, two species, Gregarithecium bambusicola, Pseudocoleophoma paraphysoidea are identified. Phylogenetically, both species clustered into a monophyletic clade with strong bootstrap support. Gregarithecium bambusicola sp. nov. can be distinguished from other species within the genus based on its almost straight ascospores. Pseudocoleophoma paraphysoidea sp. nov. differs from other species in its conidiogenous cells intermixed with paraphyses, longer conidiogenous cells and larger conidia. The identification of this lineage contributes to our understanding of the classification of Dictyosporiaceae.
