摘要

Type studies have demonstrated that despite some recent assertions in the literature, certain anamorph-genera are in need of further reassessment.Hyalothyridium viburnicolaTassi, typifying the anamorph genusHyalothyridiumTassi, is treated as anomen dubium. As a result of reassessment ofScolecosporiella typhae,Urohendersoniella, recently considered a synonym ofScolecosporiella, is reinstated. A new anamorph-genus,Orphanocoela, is proposed to accommodate three species, two of them transfers fromHyalothrydiumand one fromScolecosporiella.AmarenographiumandCallistosporaare redescribed and compared withUrohendersoniella. Conidia of members of the the last three genera have mucoid appendages that originate in a unique manner.
