Heppia Arenacea
''Heppia arenacea'' is a species of terricolous lichen, terricolous (ground-dwelling) lichen in the family Lichinaceae. Discovered in Yemen, it is characterized by its sand-coloured thallus and the incorporation of soil particles throughout its vegetative (i.e., non-reproductive) parts. The lichen is found in soil crust communities over limestone and basaltic rock in desert habitats, as well as in partially sheltered areas between large boulders. Taxonomy ''Heppia arenacea'' was first species description, formally described by German lichenologist Matthias Schultz in 2005. The type (biology), type specimen was collected by the author in Wadi Asariah, Jabal Arays (Abyan Governorate) at an elevation of approximately ; there it was found growing on exposed soil over basaltic rock under an ''Anisotes trisulcus'' shrub.

Heppia Solorinoides
''Heppia'' is a genus of olive, brownish, gray, or blackish squamulose, crustose, or peltate like lichens.Lichen Flora of the Greater Sonoran Desert Region. Vol 1, Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> ''Heppia'' was once the type genus of the family Heppiaceae, but that family was folded into synonymy with Lichinaceae. The genus name of ''Heppiella'' is in honour of Johann Adam Philipp Hepp (1797–1867), a German physician and lichenologist. The genus was circumscribed by Carl Wilhelm von Nägeli and Abramo Bartolommeo Massalongo in Geneac. Lich. (Verona) 7-8 in 1854. Description ''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. It lacks a medulla that is separate from the photobiont layer. It is a cyanolichen with the photobiont cyanobacterium being '' Syctonema'' (or ''Syctonema''-like). The lower surface ...
