I added the original photo

I added the original photo as it came from the memory chip, before I cropped it and and edited it. The color of it may be closer to the photographed fungi. I am colorblind and I cannot tell the difference. Adolf

Recognition of corticola types

perhaps there are multiple Mycena corticola types (diversified along host bark lines?), but as a group, they stand out to my eye by being more pinkish-brown to warm brown (unlike the swarms of white and gray or otherwise colored Mycena that grow on bark), and have a different stature – shorter stipes, rounder caps with more pronounced sulcation (rather than simply being translucent-striate). They also have contrasting pruinosity on both the dark cap and stipe that makes them look more like Micromphale to my eye than most other Mycena. I wonder if they will stay in Mycena or be transferred out.

This fungus appeared on the same Quercus garryana trees as Mycena corticola from earlier MO observation. Check
If it looks the same, and if it occurs on the same spot as before, it MIGHT be the same. If in doubt, check the herbarium specimen UBC F25575.

how would one ID this from just a photo?

aren’t there lots of bark mycenas out there?

I do assume that Oluna has scoped this for confirmation, but none of the other obsies here on MO have that deeper detail. Or is this truly a unique no other ID possible eyeball ID mycena?

color me skeptical.
