Observation 199428: Amanita ocreata Peck
When: 2015-02-20
No herbarium specimen

Notes: Found in soil under oaks, mostly live oak, some blue oak in immediate area. About half a dozen had emerged or were emerging in perhaps a 20-foot radius. Cap diameter: 8.5-10.5 cm. Stipe 11 cm long and 2.0-2.5 cm wide.

Caps dry, had reddish-orangish centers; otherwise white cap (tending toward buff several hours after picked). White stipe with expanded base and white sac-like volva. Stipe somewhat rough-textured in appearance; solid interior when cut in cross-section.

No annulus, but seemed to be a subtle transition from one color tissue to another in upper third of stipe.

Odor somewhat unpleasant, like stale urine or faintly fishy.

Pileus turned yellow-ish with applied 4% KOH (see picture).

Spore print white; spores elliptical.
