The amylostereum chailletii ( Amylostereum chailletii ) is a saprobiontisch living Mushrooms Fungus art from the order of Täublingsartigen (Russulales). It has crust-shaped, tomentose-brown fruiting bodies that grow directly on the bark of the infested trees. The species, which is widespread in the Holarctic , grows on spruce ( Picea ) and fir ( Abies ) in a temperate climate . It is transmitted by the giant wood wasp ( Urocerus gigas ), which keeps its oidia in its mycetangia and whose larvae it serves as food. The fruiting bodies appear all year round.

Macroscopic features
The fir layer mushroom forms crusty to effuso-reflex (wavy) fruit bodies of brown color. The edge is usually 2–10 mm from the substrate. The fruiting bodies become 0.7 mm thick and 0.5-5 cm long. Their surface is initially tomentose, later quickly bare and also covered with warts. The consistency is leathery-corky.
Microscopic features
The hyphae structure of the fir layer fungus is dimitic , i.e. it consists of generative and skeletal hyphae. The former are brownish hyaline, at their septa sit buckles . The latter are thick-walled and brown, at the top they are encrusted. In contrast to the externally very similar brown felted layer fungus ( A. areolatum ), there is no dark hyphae between the subcuticle and the lowest layer of the hymenium .
distribution
The fir layer mushroom occurs Holarctic . He prefers temperate climates .
ecology
The fir layer mushroom spreads mainly with the help of the giant wood wasp ( Urocerus gigas ), which stores its arthrospores (oidia) in abdominal organs , the mycetangia , and lays them together with their eggs in dead wood . There the fungus breaks down the lignin in the wood. The resulting white rot allows the wasp larvae to eat their way through the wood, and the fungus mycelium serves them as food . In the high European mountains, firs ( Abies spp.) In particular , and spruce ( Picea spp.) In the rest of the species area are infested .
