Thanks for the update. Sounds saprobic either way (rather than micorrhizal).

You don’t typically collect mushrooms when you go hiking? Bags and baskets work great for keeping things in good shape. Even if I don’t think I’m going to find something, I might stick a few paper lunch bags into my back pocket just in case.

Can’t help much…

I pulled up the limb they were under carefully, and they came with it, but they sure looked like they were attached to the leaves not the limb itself — could go either way in my limited experience.

I see that I didn’t note odor, but I keep forgetting to check, so again, it could go either way… certainly no strong odor.

As for spore color, pink is certainly a possibility. I was very sad to just leave this poor thing sitting on the ground when I left, but so it goes. Mushrooms just don’t survive so well in my pockets like lichens do!

I have discovered that by wrapping them in tissue and sticking them in a pringles can they can survive a long walk, especially if it’s a cool day. I will do better in the future!

I don’t usually rely on that feature to tease the genera apart, as it is often a fine line between unattached and nearly free, at least in my experience. I’ve frequently had to get multiple opinions to decide on whether the gills are REALLY attached, or just look like it.

But in that case, it looks like they are free. So then you would agree- Pluteus?

I had the same temptation, Nolanea… But being somewhat trigger-shy
tonight to throw the gauntlet at CureCat, I decided to wait a bit.

The gills seem free there, or rather I’m not sure I can see any
attachment, which if the case this is Pluteus.

Obviously they’re all pink spored and in both cases the stems can be

Of course, such a thing as a note of odor would help big time.

Microscopy would solve the Generic aspect instantaneously.

Yeah, that is also possible. As you noted, whether it was growing from the underside of the log or some other wood, versus soil is an important factor. Of course, Nolanea also assumes the spores are pink.

If this was under the log (not on the log), and has nearly free (not completely free) gills, I think that Nolanea is a possibility.

More and more observations here on MO are coming with so little information that they are impossible to ascribe to genus.

Nothing against Jason’s observations, mind you – they come with more information than most, and are photographed really nicely. I have really enjoyed this set of photos from Torres del Paine and other Chilean locales. They give me an idea of what’s out there… I’m itching to go!

Very cool looking mushroom, interesting greenish colour.

Reminds me of some Pluteus from here in California, but different colours. Did you take a spore print? The gills look pretty white, but perhaps the spores haven’t matured to buff-pink yet.
