The inedible beech corner slice ( Diatrype disciformis ) is a type of mushroom from the family of the corner slice relatives (Diatrypaceae). The wood-hard, wart-like to pustular fruit bodies appear all year round on beech branches.
features
Macroscopic features
The fruiting bodies consist of a 2-3 mm wide and up to 1.5 mm high, fairly rounded and wood-like hard stroma. Stroma is the name given to the collective fruiting bodies in ashlar mushrooms that contain several perithecia . Sometimes several stroma can grow together and appear elongated. The matt, glossy surface is dark brown to gray-brown when young, then red-brown and colored black-brown with age. It is dotted like a sieve through the mouths of the perithecia. The small fruiting bodies break through the bark, and the shreds of the bark formed into angular corners, which is also the reason for the German species name. If a stroma is cut horizontally with a sharp knife, about 20 perithecia can be seen inside. The perithecia are the actual fruiting bodies in which the spores are formed.
Microscopic features
The hyaline , smooth and allantoid (sausage-shaped) spores measure 5–8 × 1.4–1.6 µm and sit in club-shaped and long-stalked tubes. The spore-guiding part is about 15–45 µm long and 4–5.5 µm wide.
Species delimitation
The vesicular corner disc ( Diatrype bullata ) forms very similar fruiting bodies, but grows on willow branches. Species of the genus Diatrypella can also be similar . They too form rounded and pustular stroma. They differ from the genus Diatrype by their multispore tubes. Multispore means that each tube contains so many spores that the exact number cannot be determined. The warty corner disc (Diatrypella verrucaeformis), which occurs on dead, still barked branches of various hardwood species, is very similar and quite common .
Ecology and diffusion
The beech corner slice occurs all year round in dense flocks of dead beech branches that are still barked on the ground. It is particularly common from winter to spring. It rarely grows on other hardwoods. The fungus is extremely common in beech forests and can hardly be overlooked with a targeted search.
meaning
Due to its wood-like hard fruit bodies, the mushroom is not suitable as an edible mushroom.
