Deep root mushrooms are natives of North America and Europe.
Identification: These mushrooms have tall, thin stalks, 1¾-8" (5-20 cm),
and robust root systems which extend 8-10" (20-25 cm) underground. Stems lack a ring,
and there is no veil. They live on rotting deciduous wood (especially beech), though they usually appear to be growing in the
ground, deriving their nutrition from buried wood. The caps are 1-4" (3-10 cm) in diameter, yellow or
olive-brown, with wide, white gills. They produce white, cream-colored, or yellowish spore prints.
Comprehensive identification is a bit of a challenge—see Michael Kuo's site for details.
Roughly 75 people in North America are poisoned each year by mushrooms, often from eating a poisonous species that resembles an edible species. Though deaths are rare, there is no cure short of a liver transplant for severe poisoning. Don't eat any mushroom unless you are absolutely certain of its identity! Please don't trust the identifications on this site. We aren't mushroom experts and we haven't focused on safely identifying edible species.
