A minute fruticose lichen with thin branched lobes that form more or less compact brown cushions. Most commonly it grows on mossy siliceous rocks but may also occur on bryophytes on soil or tree bases. It prefers open natural habitats from lowlands to mountains. Within central Europe, P. muscicola is the most common in the Alps. It is very rare in the Czech Republic, only known from historical records, mainly from southern Moravia (Černohorský et al. 1956).
