Collection location: Lake Owen, Medicine Bow National Forest, Albany Co., Wyoming, USA [Click for map]
Growing in Quaking aspen woods, near border with Engelmann spruce and Lodgepole pine forest. Common. This gill fungus has a pleasant (I like mushrooms) fragrance, was growing on the ground. The spore print was white(ish?), the cap white tinged with faint brownish streaks (as is the stalk). I saw no evidence of any kind of veil. Very tentatively I got it to Tricholoma sp. using:

N.B.: My observation of spore print color is decidedly “on-the-fly” (from memory a day or two later of what I saw on the forest litter). Thus, I’ll follow the comment below.

Of course as everyone has said we need a spore print to make a real decision, but it looks a lot like Clitocybe nebularis to me. The gills are a bit dark/pinkish, but not out of the question. If that’s the correct id, then the odor will get stronger and more soapy/skunk-like as it gets older.
Did you get a spore print here? You’ll need that to tell the difference between Entoloma or Clitocybe/Tricholoma.
