“And it rhymes.”
So it does. Heh.

I’d like to note, that Peter Werner explained to me that our West Coast “Stropharia riparia” does not actually fit the microscopic description of the true S. riparia on the East Coast.
For lack of an alternate name, S. riparia is the name attributed to our West Coast species, though it seems to be a distinct species within the section Stropholoma (like S. riparia and S. aurantiaca).

The photos for H. capnoides are a close fit, but I’ve looked at Darvin’s spore photo of H. capnoides ( http://mushroomobserver.org/observer/show_image/2950 ) , and they seem to be a bit more irregular than what I have. Mine are almost perfectly oval and a bit more pointed at the ends — elliptical would be more accurate. From what I can see think S. riparia is a good guess. And it rhymes.

Okay, I was considering that.. I’ve not found H. capnoides, but these fit a lot of the photos I’ve seen.
The pale colour, along with the not so twisted stipe (usually they are a lot less straight than these) led me to suggest H. capnoides, over S. riparia, but since I’ve never found that species of Hypholoma, I’ll concur with you on your identification.

Has a black spore print like Hypholoma capnoides. H. capnoides generally grows in clusters and directly from wood. S. riparia typically grows singly or in small groups. It is also a composter, but grows more from mulch and rich soil. It is also a larger, more robust mushroom. S. riparia is typically a bit more yellow than these are, but these are still in the range that I’d call S. riparia.
