Distinguishing features for this subtly beautiful species of Amanita include the gorgeous pinkish orange color of the cap; the presence of delicate, powdery, pale orange patches or warts; the quickly disappearing ring; and the pale yellow stem with a small basal bulb and indistinct veil remnants. Amanita wellsii was originally described (Murrill, 1920) from the northeastern United States, but has since been reported as far away as North Carolina, Missouri, and Québec.
Ecology: Mycorrhizal with hardwoods or conifers, in diverse ecosystems; growing alone, scattered, or gregariously; summer and fall; probably widely distributed east of the Great Plains.
Cap: 3-10 cm; convex or nearly round at first, expanding to planoconvex or flat; tacky when fresh but soon dry; bald and deep pinkish orange underneath soft, powdery, pale orange universal veil material that is sometimes aggregated into patches or warts; the margin often adorned with partial veil fragments when young, becoming lined at maturity.
Gills: Free from the stem or slightly attached to it; close or crowded; whitish or pale yellow; with frequent short-gills.
Stem: 5-15 cm long; 0.5-2 cm thick; more or less equal above small basal bulb; whitish to pale yellow; finely shaggy or nearly bald; with a very delicate ring that usually disappears quickly; with soft, yellowish, patches of universal veil material on the bulb.
Flesh: White to yellowish; not staining on exposure.
Odor: Not distinctive.
Chemical Reactions: KOH yellow on cap surface.
Spore Print: White.
Microscopic Features: Spores 11-15 x 6-9 µ; long-ellipsoid; smooth; inamyloid. Basidia 4-spored; rarely clamped. Pileipellis an ixocutis or cutis of elements 2-7 µ wide. Lamellar trama bilateral; subhymenium ramose, or with slightly inflated cells.
