Abstract

Abstract: In a recent phylogenetic analysis of the family Teloschistaceae based on three molecular markers, 31 genera were newly described or resurrected. One of these genera was Parvoplaca, currently including four species in which anthraquinones may be present or absent in the apothecia. We have re-analyzed the genus and propose one new species, P. nigroblastidiata Arup, Halıcı & Vondrák, and one new combination, P. chelyae (Pérez-Vargas) Vondrák, Halıcı & Arup. The new species is known at present from Sweden, Turkey and Alaska. It is characterized by an endophloedal thallus, black blastidia produced in small spots and zeorin-lecanorine apothecia with an orange disc and black thalline margin. It is morphologically similar to Caloplaca turkuensis, but differs in the zeorine-lecanorine apothecia and the thalline margin that is dark grey-black instead of grey.
