Abstract
A new holomorphic species, Mariannaea dimorpha, is described and illustrated. The verticillate conidiophores, phialidic conidiogenous cells and aseptate microconidia that form imbricate chains indicate that it belongs to the genus Mariannaea. Sequence analyses of the combined internal transcribed spacer (ITS) and partial large subunit ribosomal DNA (28S rDNA) confirmed its taxonomic position and revealed its distinction from any morphologically similar species. In addition, the teleomorph of M. samuelsii is reported for the first time and its epitype is designated.
