What are these? Wyoming mushrooms

[fr8train]

Hello. I was wondering if anyone could help me ID these. I found them at around 9k feet.

These are very likely to be Slippery Jacks, genus Suillus. S. brevipes is the closest one that I can find; it is associated with pines. What trees were your mushrooms near?

That's what I was thinking too, but they're not like the slippery jacks I remember picking as a kid in the midwest. These were completely dry, and bright yellow, though I guess the dryness could be environmental, though it's been wet. They were growing under assorted pine.

Here are a few more unknowns that I found.

The last one posted is the same as the majority in the OP. The one with the brown cap is what was growing right next to the yellow spongy mushrooms.

Here's a shot of one of their caps:

In your first picture, looks like Suillus mixed with some Xerocomus. On the left edge of the sheet, in the middle, there is a red cap that looks from this angle like a different one and it could be Boletus Sp.

My suggestion is to clearly separate the ones you find and get familiar with the characteristics. Also, a cut helps with these types.

Yep, agree with Cedric. The boletes are a mixed collection. I see as many as 4 or 5 different species in the top photo.
