Abstract

Porpidia irrigua is described as a new species; it has a white thallus, sessile apothecia, contains the depside methyl 2'-O-methylmicrophyllinate, and grows on damp siliceous rocks. It was previously included in a wide concept of P. contraponenda, but that species differs in the thicker thallus, partly immersed apothecia, and the possession of an unidentified depside in addition to methyl 2′-O-methylmicrophyllinate, which can be separated by thin-layer chromatography using Solvent System G.
