Observation 31945: Amanita “sp-C20” Tulloss crypt. temp.

When: 2010-01-09

Collection location: Louden Nelson Community Center, Santa Cruz, California, USA [Click for map]

Who: Debbie Viess (amanitarita)

No specimen available

the first fruit body came in entirely white, with spikey warts that were not readily removed. by the next day, it had reddened after handling, then turned more of a reddish brown. the annulus is decidedly membranous, and like a novinupta, there is no volval remnant at the base. this same species, whatever it is, also came into the MSSF Fungus Fair in early December, where it was misidentified as a “cokeri”.

no herbarium specimen (damn persishable amanitas) but I will ask the folks in SC to keep an eye out and try and collect more. This looks to be a good year for it.

I am attempting to get more material.

Ah, yes, that one…

Debbie said on a posting under the older observation that she was drying a specimen. Debbie, is that one of the one’s you sent here?


I saw it

I saw this one, its not novinupta. Clearly a Lepidella. There was no red staining on it when I saw it, but there is red staining in these pictures. Interesting how it fades after a couple days. I guess its the same species as this observation.

Well, I guess we all have to start carrying around ferrous sulfate…

I am not really sure where this guy belongs, and I’m not pushing for novinupta. A number of thoughts came to mind include lepidellas. But I really don’t want to guess when I know so little.


I have never collected it…

just seen it post collection.

And always in a situation where I can’t trace back who collected it or where (ie the jumble of a Fungus Fair, w/out good collection data).

I have tried very hard to make this into novinupta myself, but it really doesn’t fit, quite.

Well, I will be rootin’ for the folks in Santa Cruz to find this again.

Greg Wright wrote that there was a species like Amanita novinupta in many ways but strongly reactive to ferrous sulfate solution (or crystal, as some prefer). Do you know anything about the habitat of this one?
