The fielded bristle disk ( Hymenochaete corrugata ) is a mushroom species from the family of bristle disk relatives (Hymenochaetaceae). It forms hard, crusty fruiting bodies that grow on the bark of hazel bushes ( Corylus avellana ). The fielded bristle disk has a Holarctic species area that also includes New Zealand . It prefers meridional to moderate climates.
features
Macroscopic features
The fielded 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 sycamore bristle disk ( H. carpatica ), this is only possible microscopically or on the basis of the substrate.
Microscopic features
The sets of the species are 40–70 µm long. Their basidia measure 12–18 × 2.5–3.5 µm and are covered with cylindrical to allantoid (sausage-shaped) spores of 4.5–6 × 1–2 µm. The microstructures of the fruiting body are therefore somewhat larger than those of the sycamore bristle disc. The fielded bristle disc has a monomitic trama and unbuckled septa .
distribution
The known distribution of the species includes the temperate and meridional Holarctic . In New Zealand it was introduced by humans.
ecology
The fielded bristle disk occurs in hazel forests , hazel bushes and on the edges of forests . As a rule, the fruiting bodies appear in spring on dead stems at heights of up to 1 m. It is more rarely found on red beeches ( Fagus sylvatica ) and red honeysuckles ( Lonicera xylosteum ). The species prefers colline to submontane locations.
