Features

Macroscopic characteristics

The firs layer fungus forms up to 1 mm thick, crusty resupinate fruiting bodies. The smooth, leathery corky - hymenium is ocher to light brown and cracked on jumps.

Microscopic characteristics

The former are brownish- hyaline, sitting at their septa buckles. The latter are thick-walled and brown, at their head, they are incrusted. The spores reach a size of 7-10 × 3-4 microns, 9-12 × 3-4 on yew also microns. A basal, parallel hyphae as in fir (A. chailletii ) and the Braunfilzigen layer mushroom ( A. areolatum ) does not exist.

Dissemination

The juniper - layer mushroom comes Holarctic of Europe to North America before. It prefers temperate climate.
