Quoted By:
Found two species growing near eachother near my house, growing on some unidentifiable buried old stump. Flatter one was growing in the grass next to the stump by itself, other one was growing right on the stump in the dirt in a small, tight cluster of ~3, this was the largest one. Any clue what they are? Flat one has brownish-pink gills, not attached to the smooth white stem. Other one has scales, with deep white gills, also not attached to the stem. Stem has a pink fixed ring. Neither had any particular smell, other than generic mushroom smell.
Doing a spore print now, will post when done. I love in the Northeast US. I think flat one might be a fawn mushroom? I checked my reference book and couldn't find anything like the one on the right.
