Hello everyone! I have attached a picture that I could really use some help ID'ing.
Was found on a hillside in very wet dirt accompanied by grass and growing in huge groups in one spot, then scattered groups elsewhere near. They were found in Northern Minnesota. Unsure if these are natural or planted by someone.
Other info: Smell: Mushroomy, shape: semi hemispherical, touch: is slightly sticky and tacky, visually smooth, they started out a creme color but started turning brown, flesh of the cap is thin on some and thick on others, the gills are crowded but visible, stems are hollow, the consistency is cartilaginous, I could not identify any rings, Spore print is BLACK.
