“Grey-brown Mycenas abound in California woodlands. Some species are gregarious on forest litter, while others fruit in troops or tufts on rotting logs. Many are difficult to identify without a microscope. Mycena amicta is an exception, at least when young. The cap of fresh specimens often shows bluish tints at the margin and disc, while the stipe base is frequently sheathed with bluish hairs and rooted when fruiting under bark. Unfortunately the bluish color which distinguishes the species is fleeting. Thus in old specimens a combination of characters is needed for an identification. These consist of a peelable, gelatinous cuticle, and at times, the formation of a collar-like ring by the gills at the stipe apex. Microscopically Mycena amicta is distinguished by the absence of pleurocystidia, cylindrical, clavate to subfusoid cheilocystidia and amyloid spores.”

My camera is horrible. Ignore all pics except top 2.

Gills in true life super light purple brown. Mushrooms were identical to other mycena in the area except for darker nipple bruising and gelatinous pellicle. Look in the top pic

Mycena amicta “…cap and stalk are blue to blue-green or tinged those colors.”
Those gills don’t look like they are going to produce dark spores.

Pic 1 captures the pellicle color the best. Also note the bluing on the stipe. Very thick gelatinous pellicle. The group shot in habitat is too white. These all blued
