Interpretive Summary: Knowledge of the diversity of microfungi particularly in tropical regions is lacking and many new species have yet to be discovered and characterized. This paper presents a description of a new genus and species of fungus related to the mycoparastie genus, Hypomyces. Found in Puerto Rico, this new fungus is described and illustrated. The distinctive ornamentation on the ascospores make this fungus particularly unique. Knowledge of the new species is useful as an aid for its identification to those who might encounter this fungus in the future.

Technical Abstract: Rogersonia zebraspora, a new genus and species of the Hypocreales (Ascomycetes) are described from decaying wood in Puerto Rico. Perithecia are similar to those of Hypomyces in that they form in a subiculum and in their perithecial anatomy. Rogersonia differs from Hypomyces in having eight unicellular ascospores in each ascus and in that R. zebraspora is not apparently fungicolous. Rogersonia is similar to Sarawakus in having eight, unicellular ascospores in each ascus and in that R. zebraspora is not apparently fungicolous. Rogersonia is similar to Sarawakus in having eight, unicellular ascospores in each ascus but differs from species of that genus in lacking a discrete stroma and in having ascospores that are hyaline. Ascospores of R. zebraspora have conspicuous, transversely arranged, raised striations. No anamorph has been observed for R. zebraspora.
