It is similar to P. tibellii and P. rufus but differs in its potassium hydroxide reaction of the thallus (K+ red) as a main distinguishing feature, additional chemical compounds detected by thin layer chromatography, and larger conical to hemispherical ascomata. Morphological and chemical differences among the closely similar taxa are discussed.}, DOI = {10.6165/tai.2022.67.267} }
