Phaeophyscia constipata does not form any vegetative propagules and is not known fertile in the Czech Republic. Thus, its populations have probably been thriving on suitable stands for a long time, depending only on lateral growth and thallus fragmentation, without the possibility of colonizing new localities. It grows on bryophytes or plant debris on calcareous substrates. The lichen occurs in the boreal zone, high mountain areas and steppe communities. It is probably a relic species and a reliable indicator of primarily open stands. It is quite rare in Europe, with continental preferences, completely missing in the suboceanic parts. In the Czech Republic, P. constipata is rare, only known from a few diabase localities near Prague. Its recent populations are very small and it is highly endangered.taxonomic classification:
