Orceolina kerguelensis

Orceolina kerguelensis is a saxicolous (rock-dwelling) crustose lichen in the family Trapeliaceae. It is the type species of the genus Orceolina. The species is endemic to subantarctic islands in the southern Indian and Atlantic oceans, where it grows on exposed basaltic and granitic rocks from sea level to alpine elevations. With its thick cortex and bright orange colouration that fades to wax-yellow in shade, this lichen is adapted to the harsh, wind-swept environments of isolated subantarctic territories....read more on Wikipedia.
