Ø vstedal, Dag O.; Gremmen, Niek J.M.
Fifteen species are reported as new to the subantarctic Prince Edward Islands (47°S, 38°E). Of these 12 are added to the known lichens of Prince Edward Island, and four are added to the Marion Island species list. Two species are new to science, viz. Gyalecta azorellae Øvstedal, with 1-3-septate ascospores, and Verrucaria efflorescens Øvstedal, with goniocysts and a massive hypothallus.
