I'm guessing G. villosipes based on the Mykoweb description: https://www.mykoweb.com/CAF/species/Gymnopus_villosipes.html

These mushrooms appear to match the description for G. villosipes in gill characteristics (adnexed to free, close, moderately broad, lighter margins), cap characteristics (color, texture, striation of the outer half of the cap, hygrophanous), habitat (growing in wood chips and redwood litter).
