Fissurina nigrolabiata is a species of lichen-forming fungus in the family Graphidaceae. It was first discovered in 2011 in the mountain rainforests of the Philippines, where it grows as a thin greenish crust on tree bark. The species has since been found in Brazil, and produces its spores in distinctive black-lipped slits that protrude slightly from the bark surface.
Fissurina nigrolabiata was first described in 2011 from montane rainforest on Luzon, Philippines, by Eimy Rivas Plata, Patrick Bawingan and Robert Lücking. The species is based on material collected by Rivas Plata on Mount Palali (Nueva Vizcaya province) at an elevation of about 1,400 m in March 2007. The specimen, numbered 1198B, is preserved as the holotype in the Field Museum herbarium (F), with an isotype (duplicate) housed in the CAHUP herbarium in Los Baños.[1]
In 2023 Pieter van den Boom, Harrie Sipman and Lücking published a second lichen from the Azores under the same binomial.[2] Because the 2011 name already occupied the combination, the later usage is an illegitimate later homonym under Art. 53.1 of the International Code of Nomenclature for algae, fungi, and plants; taxonomic databases record it accordingly and a replacement name has yet to be proposed.[3][4]
