Gyalectidium verruculosum is a species of lichen-forming fungus in the family Gomphillaceae.[1] It is a leaf-dwelling lichen known from Australasia and the western Pacific, including Papua New Guinea, Australia (Queensland and New South Wales), and Vanuatu. The species is distinguished by its triangular reproductive scales that typically develop from the inner side of a crescent-shaped crystalline bulge on the thallus surface, a feature that separates it from the externally similar Gyalectidium filicinum.
Gyalectidium verruculosum was described as a new species in 2001 by Emmanuël Sérusiaux. It was separated from the externally similar Gyalectidium filicinum by the form of its hyphophores (asexual reproducive structures), whose triangular scale typically develops from the inner side of a crescent-shaped crystalline bulge on the thallus surface. The author noted that the species had probably been overlooked in Australasia because it could be confused with G. filicinum.[2]
