Type speciesMassariovalsa sudans (Berk. & M.A. Curtis) Sacc.

NotesMassariovalsa is a saprobic genus found on woody bark. Massariovalsa was a subgenus of Melanconis (Wehmeyer 1941). Petrak (1952b) and Muller & von Arx (1962) separated the genus using the pycnidial asexual morph and the mucous epispore on the ascospores. Massariovalsa sudans was considered to be the sexual morph of Melanconiopsis inquinans (type species of Melanconiopsis) (Wehmeyer 1939, Rossman et al. 2015). Massariovalsa has integrated, enteroblastic, phialidic conidiogenous cells. The stromatic disc is not present in Massariovalsa but the conidiogenesis is similar to Melanconiella. Sequence data are not available for Massariovalsa in GenBank. Therefore, Senanayake et al. (2018) accommodated Massariovalsa in Melanconiellaceae based on similar morphology.
