Sarcodon quercinofibulatus

Sarcodon quercinofibulatus is a species of tooth fungus in the family Bankeraceae. Its specific name reflects both its ecological association with oak trees (Quercus) and the distinctive presence of clamp connections on its hyphae, which distinguishes it from related European species. The fungus produces brownish-grey scaled caps 6–14 cm broad with short cream to grey-brown spines underneath and is strictly ectomycorrhizal with sessile oak, downy oak, and European beech. Known only from northeastern Catalonia in Spain, it fruits on the forest floor of deciduous woodlands during summer and early autumn at elevations between 400–1000 metres....read more on Wikipedia.
