Thank you very much for settling the questions about this collection. Sorry I missed the roots of the two smithianas.
The specimen in the upper right of the middle photograph is silvicola. The ones with proportionately narrower stems are smithiana.
I checked the smallest specimen. It is smithiana.
So only the mid-sized specimen is silvicola.
The most expanded of the smaller specimens is A. silvicola.
So this is a mixed collection. I’m separating it into two parts. The largest specimen will be segregated as smithiana. The two collections will be accessioned separately in our herbarium in Roosevelt.
Thanks to everybody who contributed points of view on this observation.
And special thanks to Sava for sending the material for examination.
Thank you once again, Sava.
The location that you got on Google Earth is correct.
has arrived safely.
Thank you very much for sending it. You say (above) “near Browns Camp”…Google Earth shows a place called “Brown Camp” in Tillamook St. For. Is this the same spot? It is shown along Hwy 6 near the county line.
The illustrations make the situation very clear.
Changed my votes further.
Added a picture of the two bulbs. (The third mushroom from the collection I picked without bulb.) The bulb on the right is intact. The one on the left has a small piece missing, probably too small to indicate a root.
Something tells me that I’ve been corrected on this point of the annulus before…probably by Debbie.
I agree with Debbie that bulbs look complete.
I made an adjustment in my votes.
With these photos vouchered by dried material, I will not be able to forget if the Amanitaceae website has to be fixed!
The third option is open.
Rod and Debbie, thanks for your comments. I’ve seen A. smithiana before (Saturday Fall Foray the latest) and I don’t believe I was so tired yesterday to cut three smithiana roots. But I’ll check the bulbs tonight. The collection is in my fridge and I’ll also put it in the dryer (when the boletes are done).
and can see right here on MO a number of photos of silvicola that do indeed have partial veils after the cap expands. smithiana also has a partial veil that doesn’t stick around for very long…
seems to me that it is the long rooting stipe that is the best measure of smithiana as a species. Indeed, it is seldom collected in its entirety (the best example that I ever saw was one well dug up by Maggie Rogers at a long ago Breitenbush) and I link to a photo of it here…it is the large mushroom in the middle of the photo, with a button snuggled up against the radicating stipe (and even here not all of it was collected!) You can also see that many of these smithaiana also lack partial veils.
Sava’s white lepidellas do seem to have a complete bulb, at least the one that I can see well on the left. Even if you don’t get it all up, you can see where it was broken off…and i do not see that here in these photos.
I’m throwing my vote in with silvicola, but I agree, it can be a tough call.
Now if there’s yet another lepidella up there, well, that’s a whole nuther kettle of fish…;)
The presence of a fairly well structured partical veil should eliminate A. silvicola, which is described as lacking such a feature.
While the partial veil of A. smithiana is weakly-structured (it becomes very “beat up” and may disappear one the mushroom has expanded), it is apparent for a while on the stem. It is a pity that we don’t see the radicating bulb of A. smithiana in any of these shots. In the drawing in the protolog (Dr. Bas’ 1969 thesis) the radical is cut off. I can’t think of a photograph that I have seen in which the radical was not cut off in collecting or suffered some other fate.
Considering that there MIGHT be a THIRD species to consider, I’m going to give a vote to raise the probability of A. smithiana.
Sava, if you have dried material of a mature (but not over mature) specimen from this collection, I’d be interested to take a look at it…when I get a chance.
