Circinaria digitata

Circinaria digitata is a species of fruticose lichen in the family Megasporaceae. This small, soil-dwelling species is a vagrant lichen, and grows as loose, finger-like tufts that roll freely across the ground. It is restricted to high-elevation valleys of the Tian Shan mountain range in Kyrgyzstan, where it forms part of the so-called "manna" lichens – vagrant species whose thalli are not anchored to a substrate. The species was originally described in 2010 as Aspicilia digitata and transferred to the genus Circinaria after molecular work clarified relationships within the Megasporaceae....read more on Wikipedia.
