I can also make out faint reddish staining around the breaks of that distinctive volva.

hey, that’s why they call these cryptic species!

I’m still interested.

I’d like to improve my understanding of what’s what on the subjects covered by this observation and the associated comments.

Very best,

Rod Tulloss

Well…

I should have paid more attention.

Even though these are extremely white (whiter than I see for A. novinupta), they are very young in this picture and that should be expected.

The rimmed-cup bulb is something I frequently see on A. novinupta but which I have never seen on “A. ohlone”, which consistently has a relatively abrupt or tapered bulb but never a distinct rim.

So I should have suspected that these were A. novinupta. Nonetheless, I’m vouchering the specimens and will send them to whoever’s interested.

That’s terrific of you, Christian.

I’ll be getting some of these later today – I’ll bundle part of them with the recent A. novinupta I posted and send them to you, Rod.

Since there seem to multiple people interested in some dried material,…

maybe the material could be divided between interested parties?

I’m very glad to see that Christian looks to be taking up the job of shepherding a name into existence.

My interest in material is being able to make at least a partial personal interpretation of the entity and having ITS and LSU for my studies.

Christian, I’d be interested to know if the sequences for silvicola posted by Ben Wolfe et al. (GenBank) correspond to “ohlone” or to silvicola.

Very best,

Rod

just sent another example of this potential new amanita sp. off …

for DNA analysis. They have now been collected in Woodside, CA as well as in Santa Cruz, and have come into MSSF Fairs for at least two years (and were misidentified as novinupta there). I don’t know where those examples were collected.

These don’t redden so much as brown.

I am very curious as to whether these will end up in Validae or Lepidella. No question that they are unnamed.

It has been a fabulous late season save for many MR species here in the BA, and especially amanitas.

If you collect more, be sure and get fully mature forms for those all important spores. You can fluff them along at home if they aren’t mature in the field.

If it’s not too much trouble

That would be awesome. If they are what I think, they are probably
undescribed. It would be great to get more material.

I didn’t save them, but they are easily retrievable. Working today, but could possibly get them later if you are interested.

I agree with Christian’s comments.

Specimen?

Did you save these? They are the 15th Amanita species recorded in Santa Cruz in the past month.
I’m not sure that these are A. silvicola (but I’m not sure that they aren’t).
I think they are the same as the mushrooms represented in these:

Nice finds, great specimens
