03EF87AFFFD5FFC6FC34F993FD9306A8.taxon	discussion	DISCUSSION The new species is close to Gassicurtia catasema (Tuck.) Marbach, which up to recently (Santos Andrade et al. 2020). It shares the presence of lichexanthone, but differs by the red pigment inside the apothecium margin. In the key to Brazilian species of Gassicurtia by Santos Andrade et al. (2020) it would key out at couplet 5 a, differing from G. rufofuscenscens by the thallus UV + yellow due to the presence of lichexanthone. It grows side-by-side with the next species.	en	Aptroot, André, Souza, Maria Fernanda (2021): New lichen species and records from the Chapada dos Guimarães, Mato Grosso, Brazil.
