Amanita smithiana and Tricholoma magnivelare (Matsutake or pine) mushroom

(A) Amanita smithiana mushrooms cause acute gastroenteritis and delayed renal failure due to the action of the toxin allenic norleucine and may be mistaken for Tricholoma magnivelare (Matsutake or pine mushroom). Their appearance is similar to the amatoxin-containing Amanita genus mushrooms such as Amanita phalloides, A. verna, A. virosa, and A. bisporigea.
(B) Tricholoma magnivelare (Matsutake or pine mushroom) is a prized gourmet mushroom.
