Abstract

A new lichenized fungus, Lecanora microloba Śliwa & Flakus, is described from the subnival belt of the Polish Tatra Mountains. It is characterized by small, saxicolous thalli with minutely lobulate marginal areoles and mostly broadly sessile and constantly pale coloured apothecia that are grouped predominantly in the centre of the thallus. Anatomically the species is distinguished by coarse granules in the epithecium which are distinctly bright in polarized light. The species contains gyrophoric and usnic acids, zeorin and an unknown terpene as secondary metabolites.
