Probably growing from buried wood.

It did have several inches of wood debris/leaf mulch to grow through though, so I didn’t really see where it was attached.

Was it on wood?

It’s certainly not clear from the photos or from anything in the observation at the moment that it was on wood. Please add this to the notes if it’s true. I’m not familiar with Clitocybula atrialba, but based on some Google searching it seems like a good match. Of course a good number of the top photos are from Mushroom Observer (at least for me) which is cool, but potentially a bit circular.

There is a nice confirming photo at SVIMS. From Arora the final couple for this species says “Stalk clothed with dark scurfy scales; gills well-spaced; cap dark brown to blackish; growing on rotten wood or in rich humus”.

I called the ones I saw Clitocybula, but wasn’t sure about C. atrialba because they were shorter and a bit squatter. I bet that’s what this is, though. Nice find.

Clitocybula atrialba seems like a good match…

Possible Hygrophorus species

Don’t have the time to key it out, but there are a number of Hygrophorus species that look similar to this. I’d start with Hygrophorus camarophyllus and it’s close allies.

I saw a few of these collected in Monterey County last week.
Really neat species.
