Erichansenia sauronii

Erichansenia sauronii is a species of crustose lichen in the family Teloschistaceae. First scientifically described in 2004, it was named after Sauron from J. R. R. Tolkien's The Lord of the Rings in reference to its parasitic lifestyle and dark, sometimes anthraquinone-coloured fruiting bodies. The lichen is lichenicolous, meaning it grows on top of other lichens rather than directly on rock or bark, most commonly parasitizing Buellia anisomera in Antarctic environments. It forms thin, crust-like colonies that turn the host's surface units whitish while producing abundant, densely packed black-rimmed fruiting bodies with initially reddish-orange discs that darken with age....read more on Wikipedia.
