Interpretive Summary: Microfungi are diverse organisms that are not well known yet play an important role in ecosystems. Knowledge of microfungi depends on careful examination of microscopic features that result in detailed descriptions. The microfungi are given names based on those features and their biology. This paper presents descriptions and illustrations of five species of microfungi. Some of them occur on other fungi as mycoparasites while other occur on old, rotten wood of dicotyledonous trees. These results will be used to identify these microfungi when they are encountered as potential biocontrol agents or as representative of the biodiversity of fungi.

Technical Abstract: The family Niessliaceae presently includes the genera Cryptoniesslia, Melanopsamma, Niesslia, Trichosphaerella, and Valetoniella. To this assemblage are added the newly described Circinoniesslia, with C. nectriae, and Valetoniellopsis, with V. laxum. Pseudorhynchia is again recognized, based upon its type species. Melanopsamma pomiformis is redescribed and illustrated. Other newly described species are Melanopsamma verrucosa, Valetoniella pauciornata and V. claviornata. Trichosphaerella arecae is transferred to Neorehmia and that genus is excluded from the family.
