D. chilensis D. seawardii Dolichocarpus is a genus of lichens in the family Opegraphaceae.

[1] The genus was circumscribed by lichenologist Rolf Santesson in 1949, with Dolichocarpus chilensis assigned as the type species.

This species, found in Chile, grows on cactus spines in a fog desert.

[2] For several decades the genus remained monotypic, until 2008 when André Aptroot added Dolichocarpus seawardii.

This lichen, found on St Helena, forms large patches on wet, overhanging rock ledges.
