Caps up to 6.0 cm across.
Did not get a spore print but spores were light colored, hyaline in KOH under the scope, and most likely a pale yellow.
Spores ~ 8.0-9.1 X 4.7-5.8 microns, elongate and smooth with oil droplets.

A specimen would be much appreciated

This is an interesting specimen, especially for me since I have examined very little recent material from Texas. While it is suggestive of G. castaneus in a few ways, it leans more toward G. subalbellus due to the pinkish flushes on the stipe, brownish discolorations on the stipe and hymenophore, convex to planar cap that is irregularly depressed, and the slightly lumpy stipe that is enlarged toward the base. The spores I’ve seen in subalbellus are often more distinctly elongate than the spores reported here, but these are not outside the range.

If you could send a duplicate to NYBG it would be much appreciated!

I just contacted Roy via email.
I will let you know if I hear anything, unless, of course, Roy decides to get in touch with you directly.

Yes, thanks Chris, that’s why I put a low

confidence rating on them.
Let me know if that student might be interested(still around) in this collection.

should have a stipe that’s the same color as the cap. c.f. MO # 280546

Glad you saved these. One of Roy Halling’s students has been working on Gyroporus, so he would likely be interested in this collection… unless the student already graduated.
I don’t think it’s castaneus, but I could be wrong; subalbellus tends to be less brown in the pileus, but the habitat and geography of your collection support this proposal. The spore size/shape actually suggest Gyroporus sp.
