Barr (1987b) introduced Rasutoria with the type species of R. abietis which was earlier designated as Dimerosporium abietis. Species of Rasutoria are characterized by very small, globose to subglobose ascomata, surrounded by cylindrical hyphal appendages, fasciculate bitunicate saccate or oblong asci with hyaline to brown, ovoid, 1-septum ascospores (Barr 1987b). Winton et al. (2007) provided ITS sequence data for two species (R. pseudotsugae and R. tsugae) and later, Videira et al. (2017) synonymized these two species under Zasmidium due to its close phylogenetical relation with Mycosphaerella and Phaeocryptopus. We accepted Rasutoria in Euantennariaceae until it is confirmed with molecular data.
