Collection location: Jamieson Park, Poynette, Wisconsin, USA [Click for map]
cap 3 cm, stem 6 cm long, pale gray, striate. Growing near the base of a live pine tree. Spores pink, ‘nuleate’, smooth, broad elliptical, ~7 microns in longest dimension. The stem does not, however, have the yellow-brown stains from the base up that were expected from the description I have.
“nucleate” (not nuleate!), and “chrysophaeus”, not chrysopheus or whatever I said in the notes, which do not come up for editing when I hit “edit”.

Pluteus species are divided into two main groups: those with horned, thick-walled pleurocystidia and a cutis-like pileipellis; and those with non-horned, thin-walled or no pleurocystidia and a pileipellis that can be either a cutis, a hymeniderm or with upright inflated cells.
The group of the Celluloderm species do not have horned cystidia and the pileipellis is made up of club shaped to balloon-shaped cells standing side by side forming a nice closed upper surface.
For the species with a celluloderm, there is a nice key for North America available, for free:
