About Amanita magniverrucata Thiers & Ammirati
Amanita magniverrucata Thiers & Ammirati is a whitish mushroom. Its cap typically reaches up to 20 centimetres (8 inches) wide and has dark scales, and its gills are very closely spaced. The stem grows to about 7–13 centimetres (3–5 inches) long. Young mushrooms have a mild smell, which becomes unpleasant as the mushroom ages, and this species produces a white spore print. Its edibility has not been confirmed, but it is suspected to be poisonous, similar to other Amanitas in the same subgroup. While there are multiple species that resemble it, its large warts are a key feature that distinguishes it from lookalikes. This species is mycorrhizal, and forms a symbiotic association with the tree Pinus radiata, commonly known as the Monterey pine.
