Distribution

Notes
A widespread European woodland species; sources differ on its trophic interpretation, so it is left unset here.

How to separate similar species

Terracotta hedgehog is smaller and more orange-brown; its teeth are attached to or nearly free from the stem rather than clearly decurrent. Dark Sarcodon species usually have darker, scaly caps.

Interesting facts

Did you know? The toothed fertile surface is highly distinctive and quickly separates it from most gilled and pored mushrooms.
