Abstract

Bacidina mendax, described here as a new lichen species, appears to be common and widespread, at least in Central Europe. Analyses of the ITS rDNA region and the morphology of specimens showed an intraspecific variation in the new taxon. It differs from B. neosquamulosa in the lack of a subsquamulose thallus, and from B. caligans in its longer and only slightly curved to apically hooked conidia and lack of a granular (sorediate) thallus. Since ITS rDNA data support the inclusion of Bacidia pycnidiata Czarnota & Coppins in the genus Bacidina, a new combination is proposed.
