Frigidopyrenia is a fungal genus in the family Xanthopyreniaceae.

[2] It is a monotypic genus, containing the single species Frigidopyrenia bryospila, a subarctic crustose lichen.

[3] This lichen was originally described by Finnish lichenologist William Nylander in 1864 as Verrucaria bryospila.

[4] It was shuffled to several genera in its taxonomic history before Martin Grube circumscribed Frigidopyrenia in 2005 to contain it.

As of 2017, no molecular sequence data was available for Frigidopyrenia.
