Observation 168256: Amanita subsect. Limbatulae Bas

Found in the lower Turkey Creek Unit of the Big Thicket National Preserve.
Cap 7.1 cm across, somewhat tacky and difficult to remove adhering sand.
Spores were white and amyloid.
Spores ~ 11.2-15.4 X 3.9-5.0 microns, oblong to cylindric.
Q(range) = 2.73-3.53. Q(ave) = 3.15.
It had an somewhat unpleasant odor that I can’t put a name to.
With the distinctive spores, appendiculate cap margin and volva, I thought it would be an easy ID.

You will be getting this one too.

I think you should try Amanita subsect. Limbatulae.

Thanks for your suggestion to look at this page.

I think that this might be one of the taxa in subsect. Limbatulae. Something like A. praelongispora. I know that several of the taxa in the subsect. occur along the Gulf Coast and in eastern Texas. The WAO sporograph for A. cylindrispora is nearly an exact match for the sporograph produced by your data.

Those are some thoughts. You to use Bas’ key to the subsection, you need to know if there are clamps at the bases of basidia as a starting point.

Interesting collection, Ron, as you said in your email. I would be interested in seeing a portion of it.

Very best,
