Rhytisma huangshanense sp. nov. described from morphological and molecular data

A fungus collected from the Huangshan Mountains in Anhui Province, China is described as anew species, Rhytisma huangshanense. The new species, occurring on leaves of Rhododendron simsii, is similar to foliicolous species of Coccomyces but differs in having thicker epiphyllous ascomata that open by a more or less longitudinal split. Analyses based on partial small subunit or large subunit nuclear ribosomal DNA sequences confirm placement of R. huangshanense in the genus.
