Gyalectidium fuscum is a species of lichen-forming fungus in the family Gomphillaceae.[1] It is a leaf-dwelling lichen known from tropical montane regions, including Papua New Guinea, tropical Africa (Burundi and the Democratic Republic of the Congo), and northeastern Brazil. The species is distinguished by its distinctive brown-pigmented fruiting bodies, which are initially covered by a thin brown layer and later retain a reddish-brown zone at maturity, separating it from the closely related Gyalectidium filicinum.
Gyalectidium fuscum was described as a new species in 2001 by Robert Lücking and Emmanuël Sérusiaux. In the original account it was treated as closely related to Gyalectidium filicinum but distinguished by the pigmentation of its apothecia (fruiting bodies), which are covered by a brown layer when young and later retain a brown to reddish-brown zone at maturity.[2]
