Peltigera aphthosa , also known as apple lichen , is a leaf-shaped lichen .
description
The lobes of the camp are between two and four centimeters in size and are moist from a pure green color, dry brown-green to gray-green. The algae layer consists of green algae . Noticeable are dark nests of cyanobacteria , so-called cephalodia , which contain cyanobacteria of the genus Nostoc . The underside of the camp is spongy and felty and has no or only indistinct veins which, in contrast to Peltigera leucophlebia , suddenly become dark in the middle of the camp. The bearing edge is light, otherwise uniformly brown-black.
Location
The lichen grows in the high mountains (subalpine to alpine locations) and in the tundra on mosses, raw humus or moist humus soil in dwarf shrub heaths and light forests between blocks in humid locations.
