These were growing near live oak and had caps up to 6.6 cm across.
The caps were a slightly viscid and the stems were perhaps a little sticky under rather wet conditions. The stems were somewhat fibrillose but I didn’t detect any obvious cortina remnants.
The spores were ~ 9.5-10.9 X 6.7-7.1 microns and quite rough.
KOH on the cap and cap flesh was neg.
Didn’t detect any strong odor and the taste was mild.
Added some micro photos of cheilocystidium or at least what looks like cystidia. It was rather scattered in semi-clusters and fairly small in size.
It looks like these are more likely Hebelomas in spite of the spore print being more rusty than brown and their rather heavily ornamented structure.

but according to MD, the spores are “smooth or minutely roughened”.
These look much meaner.
I’d try the Melzers test, but again, my supply has expired, and unfortunately(and sadly) so has my source.
So there’s no way for me to obtain melzer’s reagent unless I get a degree and become a professional mycologist?
This sounds crazy.
Oops. read that wrong.
So I need a contact? I guess I’ll get to looking up some mycologists.
Thanks for the info.
Looking in the book “The Genus Hebeloma”, J. Vesterholt, these seem to match Hebeloma crustuliniforme just fine. Although they should have a radish odor, but you might have to cut them to get that. And the spores should be non-dextrinoid in Meltzer’s, if you even want to get around to that.
For Metlzer’s you need a contact at a mycology dept. of some university. The recipe contains clorohydrate (sp?), which is a controlled substance, so it can’t be sold on the open market.
How would one obtain melzers reagent?
What reagent did you use for the spores? Did you look at the spores in Meltzer’s?
I’d say Hebeloma, some of them have dextrinoid spores, so that would be good to know also.
Ron, this reminds me of Hebeloma. You can easily confirm/deny by looking at the lamellar edge for the typical cystidia clusters of Hebeloma.D.
