Amanita smithiana, also known as Smith's Amanita, is a species of agaric found on soil in coniferous (Abies, Tsuga, Pseudotsuga) and broadleaved (Alnus, Quercus) woodland in the Pacific Northwest of North America. It fruits in August and September. The cap has a diameter of 5–17 cm (2–7 in) and is white and scaled with remnants of the universal veil. The stem is 6–18 cm (2–7 in) and white and similarly scaled, with a ring.

It is responsible for poisonings in the Pacific Northwest when mistaken for the edible and sought after Tricholoma magnivelare. It causes rapid renal failure.[1]

Amanita smithiana was described by Dutch mycologist Cornelis Bas in 1969. It belongs in the subgenus Lepidella. Two similar species have been implicated in similar cases of acute renal failure; A. proxima in Spain and A. pseudoporphyria in Japan.
