Shield Lichen

Parmelia sulcata


Forming shield like circular aluminium-grey patches on trees, recognized by conspicuous beaten metalwork aspect of its lobes (seen well on pic N°2)


I found these on wooden hence posts along a myriade of other lichens; a hence surrounding an agricultural storage yard, just next to a protected montane stream in Jura mountain range; on edges of mixed (oak, beech, spruce and fir) forest growing on slopes.
