Two lichenicolous species are discussed: the recently described Unguiculariopsis nephromae, which occurs on Nephroma species in Canada, Fennoscandia, North America and Russia, is combined into Protounguicularia; and Hyalopeziza rapax sp. nov, is described from Pseudocyphellaria crocata in Alaska. In discussing generic placements, it is concluded that the species now known as Olla transiens is better accommodated in Protounguicularia and the species is combined into that genus. Attention is drawn to variability in general appearance of P. nephromatis, particularly the occurrence of both superficial and erumpent apothecia in the same species.
