features
Macroscopic features
The hat of the Alder-Brood has a yellowish to ocher-brownish color and is 3–12 cm wide. The matte surface is fine tomentose and usually dry, but can be a bit greasy in high humidity. It often has small, dimple-like depressions on the surface of the hat. The brim of the hat is clearly curled up when you are young, when you get older it bends up and then has a sharp edge. On the underside is the very thin, golden-yellow tube pad, which runs down a good bit on the handle. It turns increasingly olive with age. At first it turns blue at pressure points, but then turns brown. Even on the surface of the hat, the flesh turns brownish at pressure points. The tube mouths are barely visible when young, but they enlarge with age and reveal their oblong, angular structure. The tubes are stepped, so not the same length everywhere. The spore powder is ocher brown. The stem is colored like the hat, tans at pressure points and is tapered at the base. It has a longitudinal fiber pattern and is mostly curved and short. The flesh is pale yellow in the hat, but becomes brownish towards the handle. After cutting, it changes color from bluish to brownish, as is also the case on the hat. It sometimes has a sour-tart taste. The smell is insignificant.
Microscopic features
The spores are elliptical in shape, with a smooth surface, and measure 5-7 × 4-5 micrometers.
ecology
As the name suggests, the mushroom grows near alders . With this it forms a community as a mycorrhizal fungus . Because alders prefer moist, swampy locations, the alder brood can also be found in such areas. The fruiting bodies appear from August to October, sometimes en masse.
distribution
The Erlen-Grübling is the most important representative of the genus Gyrodon in Europe . It is quite rare, but widespread worldwide, including America and Asia.
meaning
The alder brood is edible, but has a low edible value. It is also "particularly protected" according to the Federal Species Protection Ordinance.
