Rock-posy or rockbright lichen is a foliose lichen, with a pale green-grey thallus. Thallus is loosely attached to the substrate, each leaf has only one point of ancrage; and the entire thallus is 10 to 15 cm in diameter, and forming a lump. The apothecia are large, and often irregular in shape, orange discs, with a contrasting rim of the same colour as thallus - here a mass of apothecia are totally covering the lump of thallus.
Seen growing on bare rocks, in a midst of other lichens, a multitude of them. Seen on slopes of one of the lower peaks of Caucasus, at some 2200 - 2300 m of altitude, and in an adjacent valley, laying at some 1900m. The valley and these slopes are regularly beaten by harsh winds, and are intermittently covered by coniferous groves, thorny shrub groves, mountain grasslands and barren rocks.
The rocks in this place were really rich in lichens - I'm only attacking the collection of shots, and have already counted (but not yet identified) over 20 differents ones... and, not being good with fungi in general, I'm really struggling with the identification; but I find it a great learning exercise...
