Technical Abstract: Fungi of the genera Cryptosporella Sacc, Ophiovalsa Petrak and Winterella (O. Kuntze) J. Reid and Booth have been reported as saprobes, endophytes and pathogens mainly from trees belonging in the Betulaceae and Ulmaceae and have recently been assigned to the family Gnomoniaceae (Diaporthales). These genera have been historically treated as closely related. Depending on the particular author and what morphological characters were emphasized, they have been considered to constitute a single genus or different genera and confusion persists today. The present study involving a selection of collections used a combination of classical morphological characters, cultural studies, and a multigene sequencing approach (ITS and RPB2) to clarify relationships. The specimens show a wide range of ascospore morphologies but formed a single clade within the Gnomoniaceae. Our results and review of the literature indicate that the fungi assigned to the three genera above represent a single genus Cryptosporella Sacc. with C. hypodermia (Fr.) Sacc. as the type species.
