Cubasina microspora sp. nov., a note on C. albo-fusca, and some new records for South America. Mycotaxon 102: 17-23. 2007.

ABSTRACT: Cubasina microspora, found on a decaying petiole in the “Serra da Jibóia”, Caatinga biome, Bahía State, Brazil, is described and illustrated. It is distinguished by subglobose conidia with constricted septa and verruculose, macronematous conidiophores. New observations are provided based on re-examination of type material of Cubasina albofusca, and 14 species of conidial fungi are reported as first records for South America.
