I think it rules out populicola :-)

measured about 8 microns long by 3 microns wide. I had help from George Riner at Alan Rockefeller’s workshop. The range for F. velutipes is 6-9.5 × 3-5. For F. populicola it is 6-7.5 × 4-5.5. The size matches F velutipes.

What microscopic features have you seen? I also have a feeling that this is populicola, but have you checked the spore size?

Flammulina lupinicola is on lupine, but usually on the immediate coast (beach)

Other than F.velutipes, what are the other possibilities?

I heard back from a Tilden ranger who said

the only native tree we have in Tilden/Wildcat that resembles poplar is white alder (Alnus rhombifolia). That’s what the log appears to be that the Flammulina are fruiting from.

Poplar? Other hardwood?
I see that Walt thinks it’s a Populus (probably P. fremontii in this location).
I think I agree with him…
