I'm fairly sure this is Lacrymaria velutina. My old field guide still has it listed as Psathyrella Velutina. I came across a bunch of tightly packed clusters of these, at work today. I didn't keep a specimen, but after looking into it, the microscopic characteristics of the spores are worth seeing. They're listed as "edible" and they had a mild nutty aroma. If I didn't have my hands full of Lion's mane and Velvet Foot Enokis, I probably would have harvested these,, because they were very hearty and looked as though they would hold their firmness for awhile.
They were cool to observe.
