Abstract:Myeloconis P. M. McCarthy & Elix gen. nov. is described from the Neotropics and the eastern Paleotropics. Four new species, M. erumpens, M. fecunda, M. guyanenis and M. parva , are recognized. The genus is characterized by a medulla containing previously unknown yellow or orange pigments and perithecioid ascomata with a dark, dense, almost pseudostromatal wall, a basally anastomosing, but otherwise free, hamathecium, uniformly thin-walled asci and elongate, muriform ascospores. While its affinities are uncertain, the ascomata and their contents suggest a rather close relationship with Porina Mull. Arg. and Clathroporina Mull. Arg. ( Trichotheliaceae ).
