Ophioparma juniperiicola, a new lichen from Spain

Ophioparma juniperiicola, a new lignicolous species, is described from eastern Spain. It is closely related with O. rubricosa by the appearance of thallus and apothecia, and the presence of divaricatic and usnic acids. The outstanding differences are in spore size and shape and the pycnospore width. Ophioparma juniperiicola is a lignicolous species with granular thallus-often reseambling isidia - and three septate ascospores, with average and size interval do not overlap with other species in the genus. A key of Ophioparma species is presented.
