Panaeolus cyanescens

I think this represents just another P. cyanescens as it does not match well with the descriptions for any of the other 7 described species within subgenus copelandia.
Basidia were both 2 and 4 spored, most of them were 4-spored. Spore length on the lower end again (12.78 × 9.54), but still within the described range [12-15(17) µm long] The fruitbody is more pigmented than it would seam appropriate to call “whitish, yellowish, isabelline” but they aren’t really dark enough to call “grey-green, Vaccine, or blackish-brown” so they are still fairly light and they may just be weathered. This mushroom looks different than (http://mushroomobserver.org/136818?q=1LsD1 ) but microscopically they seam to be nearly identical, spore averages were the same, but spore length was slightly more variable with obs 136100.
