Observation 190649: Amanita sect. Phalloideae (Fr.) Singer

Likely A. phalloides var. alba, as it was fruiting in a large patch of normally colored death caps, but it was more slender-statured than most of those, and I didn’t have KOH handy at the time so I saved in case it is A. ocreata – I don’t think there has been a fall report of that species from Santa Cruz County.

No, partially hollow with chambers

unlike a typical coccora. I have seen both A. ocreata and A. phalloides do that.
I have never seen either appear evenly hollow like the Sect. Caesareae species.

partially hollow like a coccora is hollow?

because I have seen that too, altho rarely. What I mean are literally discrete small open chambers inside the stipe of ocreata. I have never seen those in a phalloides.

I cut it in half when I put it on the dryer. I wouldn’t say A. phalloides is never hollow – I saw a partially hollow one at an FFSC foray at Quail Hollow.

Although this would be a very early record of A. ocreata, I would be less surprised now that we have finally gotten a late fall/winter record of A. ocreata for Santa Cruz: There were many at Quail Hollow on December 13, fruiting between (but not amongst) many A. phalloides. That was one of very few times I’ve ever seen those two species on the same day.

too bad …

you didn’t just use KOH on the fresh fruit body, at home or at a friend’s house or at UC. That is certainly the easiest quickest way to tell.

Did you cut it in half? Hollow chambers within the stipe are also another way to tell the diff between the two species: ocreata often has ’em, phalloides never does.

Interesting, Christian.

If you can spare a top-to-bottom piece of this material I would like to examine it. Very best, Rod
