American species; molecular phylogeny shows its not a synonym of B. titubans from Euroasia.

Likely Bolbitius variicolor

DJLodge: B. variicolor Atkinson described from the USA. This collection is a a 99.7% match for AY194535, a Michigan sequence by Heather Hallen, cited in a paper by Hallen, Watling and Adams. Watling is the World’s expert on Bolbitius so I trust this.
Perhaps this name should be resurrected for the American species.

B. lacteus or coprophilus?

See MO 565 as this looks like B. coprophilus.
Probably similar to my observation MO 378361 in same area.
