Heppia is a genus of olive, brownish, gray, or blackish squamulose, crustose, or peltate like lichens.

[3] The genus name of Heppiella is in honour of Johann Adam Philipp Hepp (1797–1867), a German physician and lichenologist.

[4] The genus was circumscribed by Carl Wilhelm von Nägeli and Abramo Bartolommeo Massalongo in Geneac.

Heppia species grow on rock or soil in arid sites around the world, in habitats similar to those favored by Peltula, which is similar but has a different cyanobacterium as the photobiont.

[2] The fruiting structures (ascomata) are apothecias immersed in the thallus with red to red-brown urn shaped (urceolate) to flat or slightly convex discs.
