Notes:
Growing in the Big Sandy Creek Unit of the Big Thicket National Preserve.
Cap 6.1 cm across.
Spore print whitish(sparse)
Spores amyloid and ~ 9.9-13.1 X 3.9-4.5 microns, cylindric to baccilform and smooth.
Q(range) = 2.48-3.15. Q(ave) = 2.75.
Seems to fit the description fairly closely of A. praelongispora.

in your description of the species on your website and was wondering how important it was.
Jenkins doesn’t actually describe it but notes that thin, membranous lobes “may or may not be appressed to top of basal bulb”
Yellow tinges on the stipe were also noted.
I did think that the spore size and Q value were a pretty good match.

Hello, Ron.

Just back and trying to get through the emails. Thanks for pointing out this posting. I’m not sure that I can see a volval limb on the top of the bulb. The species belongs in Bas’ subsection Limbatulae of sect. Lepidella. In the few collections that I’ve thought belonged to this species, there was a pretty distinct (although thin) memnbranous limb arising from the upper part of the stipe’s bulb.

Very best,

Rod
