Blewits - Clitocybe nuda these are NOT.
My brain went on vacation.

Underside  view.
George pointed out the brown deposits on the stem which is a sign that it is a Cort of some kind.

This one has a bulb at the base almost as large as the cap.

This one has brown gills and left over strands of the veil.  Another indicator that it is a Cort.  George and Gus pointed this out.

Top view of a mature Blewit.  This one did produce a pale buff spore print.

The gills are tan in color with a hint of lilac.
