Amylostereum chailletii

Fir - layer mushroom ( Amylostereum chailletii )

The firs - layer mushroom ( Amylostereum chailletii ) is a saprobiontisch living Ständerpilzart from the order of Täublingsartigen ( Russulales ). He's crust-like, tomentose - brown fruiting bodies that grow directly on the bark of infested trees. The Holarctic widespread species grows in temperate climates to spruce (Picea ) and fir (Abies ). It is transmitted by the giant wood wasp ( Urocerus gigas ), which kept its oidia in their Mycetangien and their larvae, it serves as food. The fruiting bodies appear throughout the year.

Features

Macroscopic characteristics

The firs layer of crusty fungus forms to effuso reflexes ( wavy ) fruiting body of a brown color. The edge is usually from 2-10 mm from the substrate. The fruiting bodies are 0.7 mm thick and 0.5-5 cm long. Its surface is initially tomentose, later glabrous quickly and also occupied with warts. The texture is leathery corky.

Microscopic characteristics

The Hyphenstruktur the firs layer fungus is dimitisch, ie it consists of generative and Skeletthyphen. The former are brownish- hyaline, sitting at their septa buckles. The latter are thick-walled and brown, at their head, they are incrusted. Between the Subkutikulum and the lowest layer of the hymenium itself, unlike the externally very similar Braunfilzigen layer mushroom ( A. areolatum ), no dark Hyphenlager.

Dissemination

The firs layer fungus occurs Holarctic. It prefers temperate climate.

Ecology

The firs layer fungus spreads mainly through the giant wood wasp ( Urocerus gigas ) that his arthrospores ( oidia ) kept in abdomen organs, the Mycetangien and submit along with their eggs in dead wood. There the fungus breaks down the lignin of the wood. The resulting white rot allows the wasp larvae to eat through the wood as a food serves them especially the fungal mycelium. Can be infected in the European high mountain areas, especially firs (Abies spp.), The rest Artareal spruce (Picea spp.).
