We have genetic evidence supporting the determination of this material as flavorubens.

We have obtained barcode and nrLSU (nuclear ribosomal large subunit) sequences from this material. Thank you very much for contributing this collection to our research. Several months back I reported that the flavorubens sequences seemed to indicate that all the material from within the U.S. assigned to flavorubens and sequenced in Dr. Hughes’ lab appeared to be a single species; and that is still true after tripling the number of collections sampled.

Very best,


Lovely find Bob!

I think the warts on the cap are yellow (-ish). I think you were pretty good with “flavorubens,” Bob. I’m not sure we can shed any more light on this.


there is certainly yellow on the stipe…

but I blush to confess, I am still not sure of the identity of this reddening amanita.

I caught this one with its’ pants down!

I thought this was an atypical blusher at first, but the warts are more sub pyramidal and aren’t that typical gray/pink color.

I suppose I may be a odd colored A. flavorubens. I’ve seen some strange cap colors in that species due to environmental conditions. I failed to note any “yellow crumbles” that I always find in that species around the stem base. Also, the annulus seems to lack the thickened yellow margin I see in that species.

What a Find !

it’s a reddening amanita, but sure not one that I’ve seen before.
