was split in half top to bottom.

If you can collect more, it would be good to record the smell of the flesh in the bulb at the base of the stem.

It would certainly be interesting to see a new observation with more material and more photos.

Very best,


Thought I was close

I remember Alan Rockefeller posting somthin about citrina. Unable to locate the thread. I was sure it was a citrina but computer tagged it with f. Alba. So I really don’t have any idea. I can return to the area and collect many specimens. This is not a mushroom that I have studied so I left it alone.

Very interesting, Hunter.

The current name for A. citrina var. alba is A. bulbosa. This species is believed to be restricted to Europe and western Asia. So you are very likely to have something different. Did you dry the specimen?

If the specimen is available (dried), then it would be potentially useful in a study of the citrina- and porphyria-like taxa for the world, which is currently under way. Please let me know.

If the material is not available, then I do know of one .white specimen of A. porphyria from the PNW states; however, its cap was pure white without a colored center of the cap.

I think that you might consider the possibility that this mushroom doesn’t fall in sect. Validae.

Very best.
