Than the other L. lygnyotellus observations on MO, and the L. lignyotellus from Mushrooms of West Virginia and the Central Appalachians By William C. Roody. Also that reference describes the spores as reticulate and spiny, while the spores of this observation are just reticulate. I guess the next time I find this taxon I’ll need to collect voucher specimens and check the dna.

I thought of gerardii for a while, but the gills look too dense.
