I have found this type each of the last few years in the exact same location. Occurs late in the year and persists into winter (or returns) if the weather does not get too cold.

Dug up a cluster

in the same patch today (11/28), and it was attached to a stick. (Thought for a moment it was a tuber.) So it looks to me like H. lateritium works here. I can’t really say that the stick was from a hardwood, but this bunch of spread wood/chips has been in the same spot for a few years now. Seems to me that soft conifer wood would be apt to deteriorate more rapidly.

Attached a few new photos to show the growth habit.

I see what you mean, Noah.

The one cluster seems to be attached to something under the dirt.

Try digging it up…

It looks like H. tuberosum which grows from a tough woody tuber.

Spore appear to be in the range…

6-8 × 3.5-4.5, which supports H. lateritium (formerly H. sublateritium or Naemateloma sublateritium). Spread wood chips seems an unusual habitat for this type. I’m thinking maybe there’s a buried root underneath. I have also found Flammulina in this same area, a 6 square yard “island” where two paved park roads intersect.

Looks like a pretty good match for what I was calling Hypholoma sublateritium. The coloration is much more even in a lot of photos I looked at though. I tried to propose it, but apparenty it’s deprecated and I’m not sure what to propose for that species.
