Cora casanarensis

Cora casanarensis is a rare species of basidiolichen in the family Hygrophoraceae. It is found in Colombia. This distinctive lichen forms neat, leaf-like rosettes up to 8 cm across that grow directly on bare rock, with five to eight broad lobes that change from dark grey-brown when wet to pale grey-white when dry. Described as new to science in 2014 from a single location in Casanare Department at 1400 metres elevation, it is known only from its type locality where it grows alongside mosses and other lichen species....read more on Wikipedia.
