With the clarifying publication of the name Amanita vernicoccora by Bojantchev, Pennycook, and Davis (http://www.ingentaconnect.com/...), this name now only applies to the fall coccora. This species fruits in the Fall (Nov.-Dec. with occasional records from early January) and has an orange to brown pileus and usually grows with madrone, tan oak, and Douglas fir. It has an unusually thick universal veil which leaves an ample volval sack and a thick white patch on the cap.
it rapidly fell out of favor, until the only one using it was Mike Wood. You can still find this name on Mykoweb! Some concepts die hard, I guess.
Dr. Lane described a caesar’s amanita from S. OR that was “green in all of its parts.” This is where “lanei” came from. The earliest description of a classic coccora was the calyptroderma description, so that is the current best name for this species.
We suspected that the spring coccora was a different sp. all along, not just because of its coloration, fruiting time, location and host tree, but even by its flavor! Now DNA confirms the evidence of our senses, but they are closely related; initial attempts at DNA analysis did not separate them clearly as different species.
Amanita vernicoccora ONLY refers to the Spring coccora, found under pine in the Sierra and a variety of hardwoods coastally. Bojantchev apparently found it under black oak in lower Sierra elevations, too, but pine is its far more common Sierra habitat.
Vernicoccora can also be found up into Oregon, where it has been documented for decades by folks like Jan Lindgren.
