Lesson plan

Dendrographa

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.
