Objective: In order to survey the composition of lichen flora in the northern slopes of Sierra de San Luis, Venezuela, six localities along an altitudinal gradient (0-1,400 elevation) were sampled. Methods: Lichens were collected in 60 trees from ground level to 1.3 m high on tree trunks. Results: A total of 85 species, distributed in 40 genera and 25 families were identified, representing 6.3% of the total lichen richness of Venezuela. Families Graphidaceae, Physciaceae and Porinaceae are the most diverse with 18, nine and seven species, respectively. Seventy percent of the total species have a crustose thallus. This study provides the first inventory of lichens for the region, contributing with range extensions for 46 species reported as new for Venezuela
