Collection location: Park City, Utah, USA [Click for map]

40.76° -111.59° 2350m

Who: G D Beckett (g.d.beckett@aquiver.com)

No specimen available

Maybe someone can help identify this mushroom (I’m a rookie, can’t find it in my field guide or other refs). Cap & gills white. Stem white, thick kind of like a bolete, brittle/fibrous. Slightly unpleasant odor. Found in detritus beneath stand of Fir trees. Growing in a tightly packed group of about 6 individuals. No volva, no ring evident in the young one of the two collected. Spore print in-process. Found just up from Moose Hollow near the boundary of Summit & Wasatch counties.

Thanks for any ideas.

Found another today, given that it wasn’t recently raining, it was a clearer match to Hygrophorus pudorinus. There were also many destroyed specimens nearby that looked to have been deer or moose fodder, suggesting it isn’t poisonous to them.

Danny, thanks for taking a stab at identifying the mushroom above. Neither of the specimens (one small & one large) produced any visible spore print. But, it had been raining the days before, so maybe they were just too wet. The gills were free, but otherwise it looked a lot like a Cowboy Handkerchief (which they were not, I used for visual comparison). They produced no milk, and had a “bad” mushroom odor. They were growing tightly packed and fairly deep in the detritus in a mixed woodland habitat.

The reason for my note back; when I look at photos for Agaricales sensu lato, these seem to look a lot different than the mushrooms I found (realizing wide variation in gilled mushrooms). The stem on all the individuals were as thick as boletes, the gills were sharp bladed and uniform, no veils, rings, etc.

Best regards & thank you for the thoughts.

Followup: It remained white, no bruising, and produced no visible spores on white paper.
