The sycamore bristle disk ( Hymenochaete carpatica ) is a mushroom species from the family of bristle disk relatives (Hymenochaetaceae). It forms hard, crusty fruiting bodies that grow on the bark of old mountain maples ( Acer pseudoplantanus ). The sycamore bristle disk has a European species area that extends from France to east-central Europe. It grows mainly in montane locations .
features
Macroscopic features
The sycamore bristle disc has hard, crust-like fruiting bodies that adhere directly to the bark of the host tree and can be several decimeters long. The hymenium is smooth or provided with flat humps. In young fruiting bodies it is coherent, later it tears into many tiny clods. Fertile hymenium has a rust-brown-greyish or pale cinnamon-like color and has dark bristles. The edge is initially fibrous, later it gains contour. Macroscopically, the species can hardly be distinguished from the fielded bristle disk ( H. corrugata ), this is only possible microscopically or on the basis of the substrate.
Microscopic features
The sets of the species are 60–90 µm long. Their basidia measure 15–25 × 4–5 µm and are covered with broad, cylindrical to oval spores of 5.5–6.5 × 3–3.5 µm. The sycamore bristle disk has a monomitic trama and unbuckled septa . The microstructures of the fruiting body are thus somewhat larger than those of the fielded bristle disc.
distribution
The known distribution of the species includes temperate Europe from the eastern French Vosges to Slovakia and to southern Poland to the local Carpathians .
ecology
The Sycamore Borstenscheibling occurs in summer linden - sycamore maple communities as well as in beech-maple forests. It prefers to grow in shady, air-fresh locations on nutrient-rich soils. The fruiting bodies appear a few meters high on the trunks of mountain maples on the splintering bark scales all year round; it rarely goes over to bast and sapwood . The species prefers montane locations, but also grows in the hill country.
