This was my first year in the Bear Lodge Mountains and I found the mushrooms to be abundant and delicious. It helped that it was an extremely wet year for the area. I grabbed plenty of oyster mushrooms in May and June, but I missed the King Boletes that I think came up soon afterwards in late June. I did see lots of good Boletus barrowsii and lobster mushrooms in early July. Throughout July I stumbled across a few Aspen boletes.
Later, I found a few turkey tails in late July. There were also a couple chanterelles but like the Turkey Tails, there was only one small clump. In early August the blewits started popping at the higher elevations, but I didn't like the flavor so I left those. Honey mushrooms had about a 10 day season in September and were delicious. I found them in mixed pine/aspen stands and when you find them you can usually find a lot.
Unfortunately, I never found any morels and probably missed some other good edible mushrooms, but I hope this helps fellow mushroom lovers for future years.
