Note: a holarctic, temperate to boreal-montane lichen, whose ecology and distribution are narrower than those of its host. It occurs throughout the country, exceptionally also in the Mediterranean belt, sometimes on walls, but, contrary to the host, is absent from heavily disturbed habitats. According to Vondrák (in litt.) this species is closely related to C. congrediens and C. phaeothamnos; molecular (ITS) data show that these three species could belong to a still undescribed genus, the closest outgroup being formed by C. conversa and C. conglomerata.
