Features

Macroscopic characteristics

The Oak Zystidenrindenpilz initially forms had grown - crust-like ( resupinate ) fruiting bodies that grow as crusty coatings under the branches along. Soon they stand out from the edge, and the fruit body bend slightly to the side on. The hymenium is pale reddish, flesh- colored brownish to grayish reddish purple gray and damp. It may take up about 2 mm thick swell and then has a slightly glassy- waxy. The surface is smooth or slightly tuberculate. If dry, the fruiting bodies are cracked, crusty and brittle and are then only 0.2-0.5 mm thick.

Microscopic characteristics

The cylindrical and slightly curved spores are smooth and transparent ( hyaline ) and measure 9-12 x 3-4 microns. Gloeozystiden missing, but you can find tapered, thin-walled and encrusted cystidia.

Ecology and distribution

The Oak Zystidenrindenpilz occurs in all domestic deciduous and mixed forest societies in which oaks occur naturally or have been mixed. One particularly often finds him in beech and oak forests, as well as in forests, parks, gardens and other plantings. The fungus lives sociable on the bark of dead, missing or ansitz organized but also fallen branches and twigs. The fruiting bodies can be found throughout the year. The Oak Zystidenrindenpilz is involved from the initial to late Optimal phase of Holzvermorschung. His substrate is almost 90 % oak and almost 9% beech wood, the rest comes from other deciduous trees.

Dissemination

The fungus is found in North America (Mexico, USA ), Asia (Iran, North India, Tibet, Japan, South Korea), North Africa (Morocco ) and Europe. The species is boreosubtropisch to temperat ( Subboreal ) and mainly distributed Holarctic. The fungus is present in most of Europe and is widespread in European oak area. Only in Finland, he seems to be missing. To the north, its boundary area in southern Scandinavia, where he pushes forward north to about the 60th degree of latitude.

In Germany the Oak Zystidenrindenpilz of the coast is widespread and regionally close up into the Alps. However, there are immense gaps. In addition to the inherent dispersal areas in the montane coniferous forests of southern Germany, gapes a larger gap in the area east of the Rhine North Rhine -Westphalia, the already considerable parts of Lower Saxony, the western and northern Hesse Rhineland with includes.

Importance

The Oak Zystidenrindenpilz is not edible mushroom.
