Amanita phalloides   (Death Cap Amanita)
Family
Pluteaceae
Location
North America, Europe
Dimensions
Cap 6-12 cm diameter, stem 7-12 cm tall * 1 - 1.5 cm thick
Edibility
Lethally poisonous

Description
Medium to large, fleshy mushroom with greenish olive cap, whitish stem, ring, no patches but distinctive volval sheath.

Cap Nearly round to convex at first, expanding to flat, often with a broad hump. Color greenish, with yellow or olivacreous tinges, with radiating silky fibrils.

Amanita porphyria   (Grey veiled amanita)
Family
Pluteaceae
Location
North America, Europe
Dimensions
Cap 4-10 cm diameter; stem 5-12 cm tall * 1-1.5 cm diameter
Edibility
Poisonous

Description
Medium to large, fleshy agaric, cap greyish brown or some shade of brown, sometimes with grey patches, white gills, ring, bulbous base. Grows near coniferous trees.
