|Abstract:||© 2018 Walter de Gruyter GmbH, Berlin/Boston 2018. A novel species of Morosphaeria, Morosphaeria muthupetensis, saprobic on intertidal mangrove wood of Rhizophora mucronata from Muthupet mangroves on Kaveri River Delta, Tamil Nadu along the East coast of India, is described in this paper. Morosphaeria muthupetensis is characterized by large sub-globose to lenticular ascomata; long cylindrical to clavate, short pedicellate asci; small, fusiform to ellipsoidal ascospores with acute ends when compared to other Morosphaeria species. A multigene phylogeny obtained from a combined nuclear large subunit, small subunit, internal transcribed spacers rDNA and translation elongation factor 1-Alpha sequence analysis revealed that M. muthupetensis is phylogenetically distinct and nested in between Morosphaeria velatispora and Morosphaeria ramunculicola and all these species constitute a strongly supported monophyletic clade sister to the genus Helicascus. Detailed descriptions and illustrations of M. muthupetensis are presented and compared with other Morosphaeria species.|
