Dendrographa is a genus of lichen-forming fungi in the family Roccellaceae. It has seven species. These lichens form small, shrubby tufts that cling to bark or coastal rocks along the Pacific seaboard, with brown-grey main branches and paler, pencil-thin tips that lack a protective outer skin. The genus was originally established in 1895 for a single Pacific coast species, but molecular studies in the 2010s expanded it by transferring four additional species from other genera and led to the discovery of a seventh species in Brazil.

Roccellina is a genus of lichen-forming fungi in the family Roccellaceae.

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
