Identification: Tiny brown mushrooms near Stevens Pass

Not sure what mushroom this is? Found growing on a rotting log near West Fork Miller River in Mt Baker Snoqualmie National Forest, WA.

 

Lovely wee critters! And thank you for including a good diagnostic shot of underside.
Genus Mycena. Species can be a challenge as there are many. Noting whether it smells like bleach and whether the stipe bleeds when cut can be useful.

 

Thanks again Frog! I'm going to guess M. leptocephala.
