Lecidella fuliginea is a bark-dwelling crustose lichen in the family Lecanoraceae.[1] It forms pale greenish patches on tree bark in montane rainforest in southeastern Brazil. The species is distinguished by small, round to slightly lobed fruiting bodies (apothecia) with purplish-brown to black discs, violet pigmentation in the tissues, and a distinctive xanthone (a lichen product). It was formally described in 2022 from material collected in the Santuário do Caraça region of Minas Gerais state at 1,200 to 1,400 m (3,900 to 4,600 ft) elevation. It remains known only from Brazil.
Lecidella fuliginea was described in 2022 by André Aptroot and Lidiane Alves dos Santos from material collected on tree bark in rainforest at Santuário do Caraça, Minas Gerais, Brazil, at 1,200–1,400 m (3,900–4,600 ft) elevation. The holotype (A. Aptroot 52200 & L.A. dos Santos), the reference specimen for the name, is held in the herbarium of the Instituto de Botânica (ISE). An isotype (a duplicate specimen) in kept the herbarium of the Federal University of Mato Grosso do Sul (CGMS). Within Lecidella, the species is externally similar to Lecidella elaeochroma but more similar internally to Lecidella violaceofuliginea. It shares violet pigmentation and a densely inspersed hymenium (the spore-bearing layer) with L. violaceofuliginea. Comparison with L. violaceofuliginea from the same locality (topotype material, collected at the type locality) indicated that L. fuliginea is closely related but differs in its smaller thallus and apothecia, and in having a xanthone in the thallus. These differences support treating it as a distinct species.[2]
