Kroswia

Kroswia is a genus of lichens in the family Pannariaceae. It consists of four paleotropical species: K. epispora, K. gemmascens, K. polydactyla, and the type, K. crystallifera. Species in the genus are characterized by their gelatinous, homoiomerous, and ecorticate thallus. The ascocarps contain terpenoids and fatty acids. The genus was circumscribed by Norwegian lichenologist Per Magnus Jørgensen in 2002.
The genus name Kroswia honours Hildur Krog, who was a Norwegian botanist and Thomas Douglas Victor Swinscow, a British writer, editor and physician.
