Abstract

There are limited studies on the diversity of Philippine lichenized fungi. This study collected and determined corticolous Graphidaceae from 38 collection sites in 10 municipalities of western Pangasinan province. The study found 35 Graphidaceae species belonging to 11 genera. Graphis is the dominant genus with 19 species. Other species belong to the genera Allographa (3 species) Fissurina (3), Phaeographis (3), while Austrotrema, Chapsa, Diorygma, Dyplolabia, Glyphis, Ocellularia, and Thelotrema had one species each. This taxonomic survey added 14 new records of Graphidaceae to the flora of western Pangasinan.
