Krogia

Krogia is a genus of corticolous lichens in the family Ramalinaceae. It occurs in tropical humid forests and rainforests. The genus was circumscribed by Norwegian lichenologist Einar Timdal in 2002, with Krogia coralloides assigned as the type species. These tiny lichens form distinctive coral-like cushions on tree bark, with their scale-like lobes (squamules) divided into finger-like branches that give them a miniature branching appearance. The genus is quite rare, with only six known species found scattered across mountain forests from the Caribbean to Southeast Asia and the Pacific islands.
