Extract from Wikipedia article: Hydnum rufescens, commonly known as the terracotta hedgehog, is an edible basidiomycete of the family Hydnaceae. It belongs to the small group of mushrooms often referred to as the tooth fungi, which produce fruit bodies whose cap undersurfaces are covered by hymenophores resembling spines or teeth, and not pores or gills.
Hydnum rufescens is a species of tooth fungus characterized by its reddish-brown to orange-brown cap and spines. In St. Petersburg and Leningrad Oblast, it typically grows in coniferous forests, particularly with pine and spruce, from August to October. In north-western Russia, it is commonly found in similar habitats, including mossy and humid areas, often in association with Sphagnum moss. The fungus is considered rare in the region, but can be locally abundant in suitable environments.
