Cruentotrema is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. It has seven species.
Taxonomy
The genus was circumscribed in 2012 by Rivas Plata, Papong, H. Thorsten Lumbsch, and Robert Lücking, with Cruentotrema cruentatum assigned as the type species. This enigmatic lichen had previously been described three times under different names: as Stictis cruentata Mont. (1855), as Arthothelium puniceum Müll.Arg. (1893), and as Thelotrema rhododiscum Homchantara and Coppins (2002). Molecular phylogenetics revealed its true affinities in the subfamily Fissurinoideae of the family Graphidaceae. The genus name combines the species epithet of the type species with the suffix -trema. Three species were included in the original circumscription of the genus.[1]
