Collection location: Jedediah Smith State Park, Del Norte Co., California, USA [Click for map]
These were found in the same area as MO # 14643 and also under Sitka spruce.
The caps were up to 6.9 cm across.
Sores were ~ 7.8-8.8 X 5.8-7.3 microns and with an average Q = 1.30,(13 spores)
I only found two specimens this time but the curious item was that one of them seemed to sport a small bulb at the base of the stem, much like the eastern variety, and the first time I’ve seen that in the western specimens. Or that one specimen may have gotten crushed slightly when extracting it from the ground.

It is very hard to get a sequence from the eastern material. I’m not even sure that we have ever gotten a good read from eastern material.
The pairwise difference for three nrITS sequences from western material varies from 0 to 0.557% in the limited set of data we have. So it seems to have a rather stable nrITS.
We will be looking at other genes for comparing the two taxa.
Looking forward to seeing how they compare to eastern material.
Two of your collections now have sequence numbers posted on WAO. In a matter of weeks, the sequences will be posted on GenBank for public access.
It was of good quality. Thanks you, once again, for sending us this material.
but Cristina measured spores from the more mature specimen yesterday. The spore data will change today.
Thanks again for sending the material.
Thanks again. I adjusted the techtab for your new data. I was glad to have a lat./long. That’s three more collections that have become pins on the WAO world map. I’ll get new spore data on-line soon.
Thank you, Ron.
and I do believe the flesh is white.
I did get a spore print from one of these and I believe it was a basic shade of white. I may have included a partial print in my package which is already in the mail.
Ron, your data on cap width was larger than the maximum I had recorded previously.
I find that I don’t have any data on how thick the cap is or whether the cap context is white (I guess it is) or some other color.
Have you ever obtained a spore print from any of your collections of this species?
For all MO readers: I don’t have data from recent collections concerning habitat of this species in Oregon, Washington, and other points north. I’m very interested in such data accompanying well-dried voucher material.
This species has a page on WAO at the following URL:
Thank you for emailing me about this posting. I’m not surprised that you might find a little, but distinct bulb now and then in the western species. Really, I think there is likely to be a more pronounced bulb in “babies” than one gets once stem expansion has been well underway. We find essentially apparently bulbless stems in the eastern one.
I’d like to see some of your material of this collection if that is possible.
I still need to see this in the West.
