When: 2007-12-19

Collection location: Bolinas Ridge, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

I’m posting this because I don’t recall ever seeing Amanitas fused like this …caps, annulus, and basal bulbs. Also, this is the first time I’ve found Amanita porphyrias this early and in this location, apparently under Chinquapin.

Jan Lindgren lists “raw potatoes” as the porphyria odor in her PNW key.

I came to that same odor description before I read hers. It’s pretty distinctive, but not all mushrooms nor all noses smell the same.

These California porphyria look very much like the one I know from Scandinavia. Maybe the caps are on average slightly more brownish, but everything I have seen on them is within the variations – and they are broad. If I had found these at home, I’d call them porphyria without any doubt..

California porphyria?

With respect to odor, my usual perfunctory sniff did not detect anything specific. I noticed that Thiers only says “odor mild”. I did note that the gill edges were “raggedy” which seems to equate to the more scientific term “fimbricate” used by Thiers. The spores were globose to subglobose but I didn’t have the capability of measuring them at the time. I noticed that Dimitar just posted some photos of his California collection of A. porphyria on his web site http://mushroomhobby.com/... and they look similar in color.
in this ID stroll down memory lane, did you smell this one, Ron?

porphyria has a quite distinctive odor of raw potatoes. not sure how to vote your choice up. I’m still convinced it’s our western porphyria in this photo. and if we’re rejecting names that don’t correspond with the European mushrooms, we’d best change all of those franchetii sightings to Amanita sp., too!

whatever you call porphyria in Europe…

this is what we call porphyria here (for want of a better name, perhaps).

now that you mention it tho, that is maybe why Rod didn’t like this as a porphyria either…the East can be remarkably like Europe in some of its fungi. I must say that my experience with western N. american porphyria and photos of identified material (by Jan Lindgren) causes me to stick to my original ID.

and stipe too white for what we Europeans call the real Amanita porphyria …

Rename Amanita porphyria?

With the posting of better pictures, I was hoping to rename these Amanita porphyria. However, that apparently can’t be done without a designated experts’ compliance.

Truer representation of colors

For some reason I had used my slide photos for the observation which had a little too much flash and suffered from a poor scan. I’ve added a couple of photos from my little digital which actually are more representative of the actual colors I observed. The cap color was more brownish and the annulus was definitely grayish.

I agree with Ron’s ID.

Porphyria, at least from my experiences here on the West Coast, starts out a purplish brown, then fades to paler brown and eventually to a silvery gray. The veil color looks grayish to me, too, both on the cap and annulus, which is typical of this species. Maybe the colors in the photo weren’t quite true? The abrupt volva sez porphyria to me as well.

What is your objection to this ID, Rod?
