Collection location: Littleton, Colorado, USA [Click for map]

Who: S Rausch (MileHighFly)

Specimen available
Collection number: S Rausch 19-003

Found growing in wood chips beneath cottonwood trees. It did not stain red or yellow leading me to believe it is this specie. Smells of grocery store button mushrooms but with a much stronger mushroom smell. The gills are young but already appear pink. A strong attached veil at this young age
