Notes: Under hardwoods.
Spores globose to subglobose, amyloid after 5 minutes, with a conspicuous hilar appendage. 6 – 8 micrometers.
Herbarium specimen in the Amanita 2012 bag.

have the ability to run DNA at University?
Did someone do a macro-description on this species before it got dried?
Sounds like those features are essential for a full understanding of just what this is. A small piece is only so useful, altho one can run the DNA.
here in California. Most of it will be sent to Rod Tulloss.
the friable volval remnants on the cap are certainly in keeping with other members of section validae, despite a superficial resemblence to say farinosa.
hope that you brought back a piece of this, at least.
The underside is gray with black material on the underside of the margin. A greater lengthening of the stipe in my photo has spread the gray powder out; and it is clustered on groups of surface fibrils. The specimen from Tlaxcala (of which I don’t think I have a photo) was very, very dark and more like your material. The lack of morphological data in what I have posted so far is crippling. I will see what I can do to better it. More material is probably the fundmental need. I have an offer to sequence the DNA of all Mexican material in my herbarium, which I am going to take up. This will be a help in some cases. It is highly unlikely that short collecting trips spread over about 8 years will produce a definitive collection considering the biodiversity of Mexico. The project has to be a bigger one with more players in Mexico and Mesoamerica.
Sp-18 has a brown cap with warts, this has a gray cap with powdery UV remnants. Also Sp-18 doesn’t appear to have a bulbous stipe base.
a nice set of photos of it.
and never saw it again. I believe the specimen did not survive.
I think the combined postal services of Mexico and the U.S. do not have a good record for getting material from you to me. If you’d like to keep trying, I’d love to see this collection.
