Angles captured. Two close views from slightly different angles; no shot of the stipe base.

Morphology

Egg to broadly convex button ~6 cm, warm orange to apricot fading yellower toward the margin, the surface studded with irregular white to cream patches of universal veil tissue. Still unexpanded, so gills and ring are not exposed. Base buried in moss and litter.

Habitat & substrate

Wedged among moss and leaf litter against a lichen-covered rock face and tree base. Ectomycorrhizal.

Lookalikes & what rules them out

The orange-yellow cap with loose white veil patches is diagnostic for the American yellow-orange fly agaric. A. flavoconia is yellower with more powdery, easily lost warts.

Notes

Toxic. Contains ibotenic acid and muscimol — not a species to handle casually or taste-test.
