I don’t think it’s sinicoflava…

By the time that A. sinicoflava gets this big, the volva is usually distinctly gray and even starting to look like its cracking or crumbling. When I first saw the picture of the cap alone, I had the same reaction, Dave. However, the other pictures show (in addition to the gorgeous, white saccate volva) that the cap doesn’t have the slightly sordid yellow or olive tinges that the is the basis for _sinicoflava_’s name.

I wish I could even give this one a number with confidence, but I can’t do that from a photograph…even a good one like Phil’s.

Very best,
