Tephromela superba is a species of rock-dwelling, crustose lichen in the family Tephromelataceae. It has a creamy white to slightly yellowish thallus and distinctively large blue-black apothecia (fruiting bodies) measuring up to 5 mm in diameter. Microscopically, it features a tall hymenium with purple pigmentation and a distinctive hypothecium with a wide hyaline upper layer. The lichen contains various secondary metabolites including atranorin and α-collatolic acid. It has a circumsubpolar distribution in the Southern Hemisphere, occurring in southern South America (including Tierra del Fuego and Chile), the Falkland Islands, Campbell Island in the New Zealand Subantarctic Islands, and parts of Antarctica, where it grows on rocky substrates in exposed, cold environments....read more on Wikipedia.
