stipe and calyptroderma

The cut on the stipe is not a very good one, I missed the middle all the way through the stipe. Other spring coccora were found less then 100 yards away in the same oak patch, about 8 of them. All were very young, most all in mushrumps under duff. Hope this helps.

if you collect more…

check the spores with Meltzers, a simple way to tell a Section Caesarea from Section Amidella. This does look like a possible aberrant spring coccora…volva matches, hollow stuffed stipe matches. I can’t see a striate margin, tho…

And Man, I hate calling these calyptroderma, which they wouldn’t be even if they ARE the spring coccora. You know, our pale form in search of its very own name…

isn’t solid – in the cross section you can see a stuffed cylinder.

Nathan – I also considered a pale spring coccora, but Jeff mentioned red staining (which I admittedly can’t see), and until just now I was having a hard time seeing the UV at all – now I can see that it covers almost the entire cap.

Not sure…

Not sure about Amanita calyptroderma with the solid stipe…

Amidella seems unlikely to me

I’m not familiar with this section, but based on what I could find on Rod’s Amanitaceae site (http://www.amanitaceae.org/?section+Amidella) these photos don’t seem like a good fit. While I couldn’t find an explicit description, it seems clear that the universal veil of this section is breaks up far more easily than appears to be the case here. I think it looks more like a pale spring Coccora.

Sorry man didn’t pack any home, but I can tell you exactly where they are. It’s easy to find. 37.02’11.74 N: 122.02’33.88 W or the large live oak grove at the intersection of Lockwood Lane and Graham Hill Road. Right on the side of the trail entering the groove.

If you can save (or dry) one or two specimens of this, I would love to look at them.
They may be our rare, perhaps undescribed local Amidella
