Tooth fungi (spines)

Shingled hedgehog

Sarcodon imbricatus · also known as: Scaly hedgehog, Scaly tooth

Edible

Young fruit bodies are edible; older ones are tough and bitterish. According to Wikipedia it can be poisonous raw – always cook it. Name: since 2003 the recommended Polish name is “sarniak świerkowy” (S. imbricatus, under spruces); the very similar Sarcodon squamosus grows under pines and is distinguished mainly by the tree – foragers call both “sarna” (“roe deer”).
