Ingaderia is a genus of lichen-forming fungi in the family Opegraphaceae. Species in this genus form pale, crusty patches that often crack when thick, and produce elongated fruiting bodies that appear as narrow slits on the surface. The genus was originally established with a single species from South America, but molecular studies published in 2023 expanded its scope to include several species previously classified in other genera such as Llimonaea and Paraingaderia. Species are distinguished by their thick, dark fruiting body walls, elongated ascospores divided by cross-walls, and the presen

Ingaderia is a genus of lichen-forming fungi in the family Opegraphaceae. Species in this genus form pale, crusty patches that often crack when thick, and produce elongated fruiting bodies that appear as narrow slits on the surface. The genus was originally established with a single species from South America, but molecular studies published in 2023 expanded its scope to include several species previously classified in other genera such as Llimonaea and Paraingaderia. Species are distinguished by their thick, dark fruiting body walls, elongated ascospores divided by cross-walls, and the presence of various lichen products including erythrin, gyrophoric acid, or lecanoric acid. The genus comprises eight species found primarily in warmer climates, growing on rocks or bark.
