Picture taken at Targasonne, Oriental Pyrenees, France, on a granite boulder, with Dimelaena oreina, 1.650 m altitude.
This lichen appears upland in the Pyrenees, being frequent in Catalonia.
It is very variable and it is very useful to enter Lichen Gallery (Leif Stridvall). You will see different forms of the same species. My congratulations to Leif for the wonderful work done.
In Historia Natural dels Països Catalans , Fongs i Liquens, in pag.414 there is a very good picture of Dr. Javier Etayo.
