Curve from 439 observations (GBIF: Poland, Czechia, Slovakia, Germany), smoothed week by week. It shows when foragers most often report the species, not how much of it grows.

Key features

Fruit body shaped like a donkey's ear: elongated, split on one side, ochre yellow with a pinkish tint of the hymenium (diagnostic feature). Grows in clusters on litter in deciduous forests, especially under beech and oak. Of no culinary importance, but with a characteristic silhouette.
