Notes: Dematiohelicoma was introduced based on morphological and phylogenetic analyses. The conidia of Dematiohelicoma are characterized by hyaline or subhyaline basal cells, tapering gradually towards a truncated base, while the remaining cells are reddish brown, and their conidial septa are dark brown and obviously darker than the adjacent parts (Lu et al. 2018b).
