Abstract

Two new Polycoccum species are described from Turkey: R aksoyi on the areoles of Aspicilia cinerea, and R acarosporicola on Acarospora cervina. R aksoyi is characterized by ascomata with a very small ostiole with a pale brown lower part, smooth ascospores with a thin (0.5 mu m thick) colourless gelatinous sheath, and the host: a member of Aspicilia. R acarosporicola differs from all species of the genus in the host selected (Acarospora cervina) and from R cartilaginosum in the narrower and differently shaped ascospores. The single previous report of R cartilaginosum from Turkey is a misidentification for the species now named P. acarosporicola.
