Observation 8907: Amanita brunnescens G.F. Atk.
When: 2008-08-09
Herbarium specimen reported

Notes: Amanita found in upstate New York. Need help here, I have no idea what it might be. Sorry, on this one the base was lost, it was a little old, and the base had mostly fallen apart, so that feature is unknown.

9/4/2008 – Was able to look at spores on Aug. 30 -

Put a piece of the veil tissue under the scope to look for spores. The micro-shot is of veil tissue at 1000x in Meltzer’s. The spores here are globose and amyloid.

Measuring the spores, I found 14 spores and determined the ave. spore size : length – 8.04 +/- 0.42 (err 0.12) um, width – 7.70 +/- 0.41 (err: 0.12) – q : 1.05 +/- 0.05. The Q is close to 1, the spores are really globose.

Not sure if this helps make the id here…

I’d guess that it belongs in either sect. Phalloideae or sect. Validae.

In the NE US, it could be Amanita solaniolens….
