Cetraria ericetorum is a species of rock-dwelling, lichen-forming fungus in the family Parmeliaceae. It occurs in Europe and North America.
The species was validly published by the Czech-German botanist and forester Philipp Maximilian Opiz.[1] He had published the species earlier in 1823, but that earlier mention was not validly published because it was unaccompanied by a description or diagnosis, so the name dates from its valid publication in 1852.[2]
In molecular studies, Cetraria ericetorum has often been treated with Cetraria islandica as part of the C. islandica species complex. An nrITS-based phylogenetic study published in 1998 found that European and North American material of Cetraria ericetorum differed at only a few DNA positions, and that C. ericetorum and C. islandica were only weakly separated.[3] A later study likewise found that the widely used nrITS barcode did not reliably distinguish the two species, although the RPB2 barcode separated C. islandica from C. ericetorum with a barcode gap.[4]
