Clathroporinopsis

Clathroporinopsis is a single-species fungal genus in the family Gyalectaceae. Its sole species, Clathroporinopsis nidarosiensis, is a crustose lichen that grows on dry, rain-sheltered calcareous rock and masonry in western, northern, and parts of central Europe, as well as Iceland. The lichen forms a thin, pink-orange crust whose photobiont belongs to the green algal genus Trentepohlia. Fruiting bodies are uncommon, and the species is often encountered as broad sterile patches that can be mistaken for algal films. The genus name was coined by Maurice Choisy in 1929 but remained obscure for decades; the species passed through Clathroporina, Belonia, and Gyalecta before molecular and morphological evidence led to the recognition of Clathroporinopsis as a distinct genus in 2024....read more on Wikipedia.
