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.
The genus name of Krogia is in honour of Hildur Krog (1922–2014), who was a Norwegian botanist.[1]
