Cladonia graeca

About

Cladonia graeca is a species of saxicolous (rock-dwelling), fruticose lichen in the family Cladoniaceae. Found in Greece, it was formally described as a new species in 2011 by lichenologists Harrie Sipman and Teuvo Ahti. The type specimen was collected by Sipman and Thomas Raus from the summit area of Mount Ochi (Euboea), at an altitude of 1,370 m (4,490 ft); it has also been recorded on the island Thasos. The small and inconspicuous lichen grows on boulders and cliffs of siliceous schist, especially in areas where downward-trickling water collects in dwarf shrub vegetation. It is similar to C. macrophylla and C. decorticata, but differs chemically from those species, as it contains fumarprotocetraric acid rather than psoromic acid or perlatolic acid.
