Heppia is a genus of olive, brownish, gray, or blackish squamulose, crustose, or peltate like lichens.[2] Heppia was once the type genus of the family Heppiaceae, but that family was folded into synonymy with Lichinaceae.[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. Lich. (Verona) 7-8 in 1854.
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] It lacks a medulla that is separate from the photobiont layer.[2] It is a cyanolichen with the photobiont cyanobacterium being Syctonema (or Syctonema-like).[2] The lower surface is paler than upper surface, and has numerous rhizoidal hyphae attaching it to the substrate.[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.[2] An exciple may or may not be present.[2]
