(Acrogenosporaceae, Minutisphaerales) Appears to Be a Very Diverse Genus.

During a study of diversity and taxonomy of lignicolous freshwater fungi in China, nine species of were collected. Seven of these were new species and they are described and illustrated. With morphology, additional evidence to support establishment of new species is provided by phylogeny derived from DNA sequence analyses of a combined LSU, SSU, TEF1α, and RPB2 sequence dataset. and were re-collected and sequenced for the first time. The genus is far more species rich than originally thought, with nine species found in a small area of Yunnan Province, China.
