Observation 68208: Amanita calyptroderma G.F. Atk. & V.G. Ballen

When: 2010-06-17

Collection location: San Bernardino National Forest, San Bernardino Co., California, USA [Click for map]

Who: shrimage

No specimen available

Found here growing in a fairy open exposure(which isn’t always the case for this one) of Fir/Pine/Oak Montane Mixed Coniferous Forest at approximately 5500 ft. elevation in the San Bernardino National Forest in San Bernardino Co., California. Pictures show tree litter around the mushrooms from California Black Oak(Quercus kelloggii, Yellow Pine with both Ponderosa Pine(Pinus ponderosus) and Jeffrey Pine(Pinus jeffreyi) (Yellow Pines) occurring nearby, also some small growing Incense Cedar(Calocedrus decurrens) seen pictured. Also common nearby are Sugar Pine(Pinus lambertiana), White Fir(Abies concolor) along with Canyon Live Oak(Quercus chrysolepsis) among others.

These were found quite buried with just the slightest shrump/hint and had to be excavated. Caps showing universal veil remnants on them along with striated margins. The volva/cup at base of stem/stipe exhibiting the “inner collar” or “secondary sheath” structure Mrs. Ballen had also observed for these originally which is a very common occurence with this mushroom locally.

This is a very choice edible IME. Also reffered to by the common name “Coccora”


Excavation underway
