Most darker spores are going to show up on the stem. Rusty brown shows right up and if you blow these pics up you see no such spore color on the stem. If the spore color was a lighter color like white or yellow then it makes it difficult to see it.

The print will be light. I never trust the spore print color reported by a new user until they prove to me that they know how to make a spore print.

Distinctly sinuate-attached gills. I have found both Melanoleuca and Pluteus on wood mulch.
My vote is against Pluteus, but that leaves an unexplained spore print. Any chance of a mix-up with another specimen set out for spore printing? These don’t look like they should be brown-spored.

Isn’t there one big problem with calling this Pluteus?

Namely, that they’re terrestrial. Pluteus are lignicolous.

Melanoleuca gives a white spore print. Pluteus gives a pinkish brown that can be mistaken for rusty-brown. The gills are close, not crowded. The stipe is too thick for Melanoleuca and the fading of the cap colors seem like a perfect fit for Pluteus. My first impression (gut feeling) was Pluteus. A photo of the spore print would tell for sure.

Darvin, why Pluteus??
I think Irene has it with Melanoleuca… which species is a bit trickier.. They all look the same and all the available names are European taxa. These are distinctive at least in that they are fairly large.

Rusty-brown spores?

Are you sure? This looks like a Melanoleuca to me (spores white to yellowish).
