Description
Graphis crebra has a corticate
The main secondary compound in Graphis crebra is norstictic acid.[2]
Similar species
Similar species include Graphis cincta, which lacks open pruinose discs, and G. handelii, which does have open discs but is not pruinose. Another lookalike species is the Australian G. streimanii, which has larger spores and lirellae that are longer and more branched.[2] The species G. manipurensis and G.sirohiensis, both known only from Manipur, India, are also similar in appearance to Graphis crebra. The Indian species, however, do not have the white pruinose disc characteristic of G. crebra.[4] Another pantropical, norstictic acid-containing species, Graphis handelii, can be distinguished from G. crebra by its epruinose apothecial discs.[5]
