Stunning and rare specimen, growing solitary in sandy soil, grass and moss, southeast Michigan. Base of stipe bruised blue immediately when plucked from the ground. Pholiotina/Conocybe smithii? Or is this perhaps Pholiotina/Conocybe cyanopus? Found more of what I believe to be the same species nearby, however they were less mature mushrooms and appear as if they may be a different species (later group pictures removed).

growing near white pine, recently cleared area, light brown spore print, blue bruising where damaged. On the border of the Northeastern sands and Northern Lake Michigan Coastal ecological landscapes. Growing alongside Panaeolus foenisecii, Panaeolus cinctulus, Aleuria aurantia. and Conocybe tenera.
