Abstract:
Pseudocosmospora species typically occur on stromata of diatrypaceous and xylariaceous fungi and are mainly distributed in tropical and temperate areas. Some of them play important roles in biomedicine and agriculture due to their production of bioactive secondary metabolites. In this study, Pseudocosmospora chlamydospora sp. nov. and P. chloroxantha sp. nov. from Beijing, China are described based on morphological features and phylogenetic analyses of combined ITS, LSU, tub2, rpb1 and tef1-α sequences. Detailed descriptions and illustrations of the novel taxa are provided, and their distinctions from close relatives are discussed.
