These were found growing directly from dung by weiliiiiiii. Workman confirmed that these match P. castaneifolius and his microscopy composite is posted with his permission.

We are now calling the collections which used to go by P. castaneifolius P. olivaceus.

Odor of mushrooms were slightly farinaceous but on the sweeter side if that makes any sense.
Strong blue bruising and much stronger blue bruising in pinners.
Strong mycelial connection to old buried wood chips. Stem was very white and hard to break in half, rather it would splinter if severely damaged.
Distinct purple brown spores.
Growth was halted for many due to the large decrease in temperature. Night prior was 35° F and the temp when observed was 45° F.

Single basidiocarp growing on a hardwood log in a floodplain near Platanus occidentalis, Populus deltoides, Asimina triloba, Acer negundo, Aesculus flava and Ulmus sp. Cap changing from dark brown when fresh to bluish gray; 6.1 cm wide. Basidiocarp 5.3 cm tall. Stem and gills bruising slowly blue. Young gills white before changing to pink. Pileipellis a cutis with clamp connections between the hyphae. Pleurocystidia strongly hooked. This seemed unusually robust for P. americanus to me but it seems like a decent match microscopically.
