Observation 140575: Amanita austrostraminea D.A. Reid

This observation includes some lavender discoloration on the surface of the bulb.

Collected and photographed by S.J.Greco.
Those are her accession numbers in the photos which I believe were used to derive accession numbers at amanitaceae.org where these samples now reside.

The material has yielded a .very nice nrLSU sequence (and probably other sequences that I have not seen) as part of the “5,000 Agarics” project that has been underway for several years. The signatures for that project have not been released to GenBank so far as I can tell.

Very best,
