Maybe Hydropus

rough guess on account of gills turning black or sooty.

spore data also supports Hydropus – smooth, hyaline, elliptical, “inamyloid”. Although many of the details I’ve read this morning on Hydropus species mention inamyloid to weakly amyloid.

Habitat fits nicely for some species of Hydropus as well.
