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

A fungus collected from the Huangshan Mountains in Anhui Province, China is described as a new 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.
