Tricholoma species

After reading Steve Trudell’s article “The Genus Tricholoma in North America”, and reviewing other sources, I agree with cmcassidy’s proposed name for genus. Trudell mentions “gills of unequal length and emarginate or rounded where they approach the stalk”. He also says some species are malodorous, with some smelling like coal tar. I stated that the odor was paint-like and unpleasant. I have never smelled coal tar, but the phrase “old motor oil” did cross my mind when I smelled the specimen.
