Recognized by sight: Just added this as a suggestion-altho most all characteristics pointed to Galerina(minus gill splits. I have found drab, dusty(large) Tubaria furfuracea that macroscopically looked like G. marginata in Fall historically. The dark, almost bluish, gray stems are dead giveaway usually for Galerina marginata group. K. vernalis perhaps?

The lowest arrow on the right

points to a spore deposit on the wood beneath the mushroom. Also, the other arrow points to loose, clumped spores on the front of a cap. That does looks somewhat similar, but not super close. The spore deposit was reddish purple but I found these over a year ago and did not collect them, so I can’t do anything more with them.

If the darker color on the lower cap….

is due to a spore deposit from the upper one, then you should be able to scrape a bit of spore from the deposit. Otherwise, the photo does not make clear to me that the discoloration is due to a spore deposit.

My Tubaria suggestion was mainly meant to provide a reasonable alternative to G. marginata for this post-mature fruiting. Reviewing some of my own G. marginata IDs, this does look more like G. marginata. For example obs 157829.

has visible spore deposits. I added a closeup with arrows pointing to spore deposits too.

Where is the reddish purple spore print visible in a photo?

I thought maybe “Tubaria” for these. Spore print for T. confragosa reported as brown to rust-brown. T. furfuracea has an ochre print.

Galerina?

I know this does look Galerina-like, and that’s what I thought what I first found it, but the spore print is reddish purple, not rusty brown, and the gills are branched. Do any Galerina species have these characteristics?
