Specimens this year were to be delivered by 8AM for identification process. Drs. Lorelei Norvell and Judy Rogers were present working on various identification tables when I got to the show at 10AM, and the show opened at noon. I didn’t see Janet Lingren this year, but she is usually near the Amanita table. The only fungi I helped identify were Daedalopsis confragrosa, Scleroderma areolatum, and S. cepa.

Finally, towards the end of the show the crowd thinned out enough at the truffle table that I could leave Adrien Beyerle and take pics for 30-40 minutes. Even so, I don’t think I got everything on display.

I certainly am in awe of Rod Tuloss, and grateful to have him look at any bad pictures I take. It does bug me that my camera may not be taking accurate color photos of the displayed material. But I remember this collection having a slightly lighter brown coloration than shown in the photo. Otherwise it looked the same. I didn’t notice any yellowing of the flesh. I remember it was one of the more interesting specimens displayed, both in pristine appearance and you had to look twice to see any volvol patches on the cap. The base was hidden under moss, so can’t relate any helpful hints there. Next best thing is to ask for some of the dessicata for identification from Dr. Lorelei Norvell, who runs the OMS Herbarium.

sure woulda been nice to have seen this amanita in its entirety…

it does bug me that it gets a farinosa moniker, altho I realize this just might be what you have been calling this distinctive and different amanita of the PNW; beats Amanita sp., which really tells you nothing!

Was it brown when collected, or did it brown with time and handling?

And of course, Fair ID is a whole nuther animal…quick, dirty and not always spot-on…gotta produce under the gun for SHOWTIME! Just the nature of the beast, no matter where the Fair…

If it’s cocoa brown, is it farinosa sensu auct. PNW?

The summary line, above, holds the next question.


has pictures and most of the data that I have on this mushroom.

There’s nothing about cocoa brown powder. Was the flesh yellow-staining?

Very best,


It was mostly cocoa brown in my opinion.

There were hints of dull red as well, but mostly dry cocoa powder, both cap and volvol patches were concolorous. There should also be dessicata of this specimen available shortly from Dr. Lorelei Norvell, who is curator of the OMS Herbarium collection. I don’t think this is the first display of A. farinosa at an OMS Fall Show. We have never had such an extensive collection A. phalloides before, though. Dr. Judy Rogers mentioned she was finding A. phalloides in mixed Douglas-fir stands now as well. I don’t remember where she said the collections were coming from.

Cocoa brown?

Is this true color?

I have never heard of cocoa brown as a color of this mushroom.

Can you tell us more?
