Yet another North American species of Amanita currently going under the name of a classic European species, "Amanita crocea" on our continent parallels its European counterpart in preferring hardwoods, and in its distinguishing physical features, which include a pale orange, striate cap; a gorgeous, ring-less stem covered with pale orange chevrons and fibrils; and a sacklike, membranous volva.
Ecology: Mycorrhizal with hardwoods (especially oaks and birch); growing alone or scattered; summer and fall; widely distributed in North America as a species group (see comments below).
Cap: 3-13 cm; convex, expanding to planoconvex or flat; pale, dull orange to dark orange; sometimes developing a brownish center; tacky when wet; bald; the margin strongly lined for 1-2 cm at maturity.
Gills: Free from the stem or slightly attached to it; close or crowded; whitish; with frequent short-gills.
Stem: 6-15 cm long; 0.5-2 cm thick; tapering slightly to apex; covered with pale orange fibrils that often become arranged into chevrons or scaly patterns; without a ring; without a swollen base; with a sacklike, whitish volva that features an orangish inner surface.
Flesh: White; unchanging when sliced.
Odor: Not distinctive.
Spore Print: White.
Chemical Reactions: KOH on cap surface yellow, then olive.
Microscopic Features: Spores 8-11 µ; globose or subglobose; smooth; inamyloid. Basidia 4-sterigmate; without basal clamps. Pileipellis an ixocutis of hyphae 2-6 µ wide. Lamellar trama bilateral; subhymenium cellular.
