Echinodontium tinctorium, commonly known as the Indian paint fungus or toothed conk,[1] is a species of fungus in the family Echinodontiaceae. It is a plant pathogen. Found on tree species such as grand fir (and indicating a rotten core).[2]
Description
Growing to 8–20 centimetres (3–8 in) wide,[3] it can be identified by the grayish spines of its lower surface.[2] The flesh is reddish-brown and woody.[3]
Similar species
Similar species include the rare Echinodontium ballouii, as well as various conks which have pores rather than teeth below.[3]
Uses
Native Americans used the red interior as a pigment.[2] Some Plateau Indian tribes applied the fungus to skin to prevent it from chapping.[4] It is inedible.[5]
