Abstract: The new species Rhytidhysteron vincekii is described. It was collected on periodically dry (xeric), recently dead, corticated twigs and branches of Prunus cerasifera at a single site in the lowlands of Montenegro. At first sight, it is morphologically similar to R. rufulum, with which it shares similar-sized, 3-septate ascospores, while showing merely slight macro- and microscopical differences, such as colour and spore size. However, our molecular analysis gave us the basis to treat it as a new species, which surprizingly clustered distant from R. rufulum in a clade with two species with 1-septate ascospores, R. hysterinum and R. xizangense.
Spegazzini (1881) erected the genus Rhytidhysteron and placed R. brasiliense Speg. and R. viride Speg. in it, without mentioning the type. Later, without any explanation, he used the name “Rhytidhysterion” (Spegazzini, 1888). This change was not accepted because the International Code of Botanical Nomenclature 1972 (Art. 73) dictated that the original name Rhytidhysteron must be retained. Clements & Shear (1931) chose R. brasiliense as the type of the genus, by placing Rhytidhysteron in the Dermataceae […]
