Observation 67508: Amanita aprica group

This was found under the canopy of a Ponderosa Pine (Pinus ponderosa) tree in a stand of montane mixed coniferous including Sugar Pine(Pinus lambertiana), Black Oak(Quercus kellogii), Incense cedar(Calocedrus decurrens), White Fir(Abies concolor) also present.

It was approaching dark when found, pressed for time…could only get a few pictures and with terrible quality. Noticibly missing among other things are partial veil details.

Threw a hand in there for some scale. That cap diameter at widest was slightly over 8.5 inches.

These have been found occasionally for several years in that general area of the Transverse Range and the Northern Penninsular Range in San Jacinto area.

Could also be expected possible to Mexico in similar habitat of the Penninsular Range.

with that bright cap and cupulate volva it does indeed resemble an aprica.

are the warts growing into the cap? i.e. if you scrape them with a fingernail, are they difficult to remove from the cap surface?

do you also have the ability to get spore drop and look at spores under a scope?
also, it would be good to dry a mature example and get it to a local herbarium.
looks like a potential range extension for this…

did you dig it up?

we need more info for a good ID here…did you see corroborating details for an aprica ID in the field? cap color is not enough to go on.

the San Bernadino Mts. would be an extension of the known range of aprica, which is considered to be a PNW/Sierran species.

have the prior examples that you claimed to have seen in the area also been carefully examined, and how did you make your species determination?

it is certainly reminescent of an aprica, but…
