Coprinus, coprinellus, ... bulbous stipe ?

[BubikolRamios]

Black gills edge pops out only with fill light, natural light - all almost black.
On top of dead tilia wood, inside moss.

In the past, people would have said, this is either Coprinellus domesticus or ellisii, but there are apparently more species – distinguishable only genetically.
So: Coprinellus sect. domestici

The slightly swollen stipe and especially this rim (where the velum has torn off) are typical.
Maybe we see a bit of orange ozonium as well.

Maybe we see a bit of orange ozonium as well.

Maybe, opened with irfan no orange, opened with PS, RAW, + fill light I get that orange.
I guess if I would have vivid instead of neutral on camera, orange might appear right out of the box.

Also landed at Coprinellus domesticus. Local desc. mentions wood & solitude growth, which fit.

AI pulled somewhere from FB claim that C. micaceus often forms bulb and/or hair rim there, I gues that would go for all coprinellus, sample of that hair & hidden bulb I guess.

Yes, “wood and solitude growth” is correct for Coprinus domesticus, and the size is o.k. as well - but this is currently a group of species that cannot be distinguished macroscopically or microscopically.
C. micaceus and similar species - such as C. saccharinus and truncorum - are not member of this group; they are (most times) smaller with gregarious growth and have those “shimmering grains” (velum remnants) on their caps.
The velum remnants in the C. domesticus group aren’t shimmering. They are small, unregular brownish shreds that you can clearly see in your photo.
