Rhizocarpon (Various species), Map Lichen, Kartlav.
Very common yellow/green lichen found everywhere in the mountains.
It is normally in colonies which often merge, separated by a black band. Once rock has been exposed by a glacier it takes about 20 years to become established and then grows at a rate of 1mm each year.
Scientists can therefore use it to measure glacial changes since the mini-ice age 250 years ago.
A crustose lichen.
