Umbilicaria sp
Light-grey to darker-grey foliose lichen, leaves fixed to substrate in one point. I thought of Umbilicaria subglabra
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.
