Cora undulata

About

Cora undulata is a rare species of basidiolichen in the family Hygrophoraceae. It is found in Colombia. Its dark olive-green thalli are foliose, measuring up to 9 cm and comprising 5 to 15 semicircular lobes. This lichen gets its name from the wavy, rippled surface of its lobes and is characterised by whitish to pale orange-brown fertile patches on its underside that form rings mirroring the ridges above. Described as new to science in 2014 from a single location in Casanare Department at 1400 metres elevation, it is currently known only from its type locality where it grows on rocks among mosses in semi-exposed habitats.
