Imsharria is a fungal genus in the family Lecideaceae. It comprises the single species Imsharria orangei, a rare saxicolous (rock-dwelling), crustose lichen. Endemic to the Falkland Islands, the lichen can be recognised by its sunken brown apothecia (fruiting bodies) and grey thallus with its distinctive paler margin. It is usually found on or near mountain summits, particularly in areas of broken rock (stone runs) and sparsely vegetated rocky ground (feldmark).
