A relatively rare lichen usually found on basic silicates. It has prominently brown and shiny thallus of convex areoles or squamules. On those, often composite black apothecia are formed. It is more or less clear from the overall habitus that this lichen does not belong to the genus Lecidea s. str.
Lecidea fuliginosa overgrows crevices in low, sun-exposed basic rocks at higher elevations. It has been reported mainly from western-European countries. Less than ten historical records are mentioned in the Catalogue of Lichens of the Czech Republic (Vězda & Liška 1999). However, most of them were misinterpreted already in the original publication (such as the confusion of L. fuliginosa with L. fuliginea currently belonging to the genus Placythiella), excerpted by mistake or obviously refer to other lichens. The only original record is probably that of Eitner from the Kotelní jáma in the Krkonoše Mts (Eitner 1896).
