Information from the abstract
Freshwater fungi in Annulatascaceae represent a morphologically diverse but taxonomically challenging group, with several genera remaining poorly defined due to morphological convergence and a lack of molecular data. In this study, two novel species, Annulatascus dongtingensis sp. nov . and Fusoidigranularius dongtingensis sp. nov ., are introduced from Dongting Lake in the mid-lower Yangtze River basin, China. Among them, F. dongtingensis broadens the known morphological variation of the genus by exhibiting a vertically oriented ostiolar neck. Maximum likelihood and Bayesian analyses of ITS, LSU, and SSU sequences showed that both species represent distinct lineages. Annulatascus dongtingensis formed a sister clade to A. hongkongensis and A. thailandensis , whereas Fusoidigranularius dongtingensis grouped with its type species, F. nilensis .
