That is NOT a Mycena! It’s sitting on the Mycena! I took a picture for someone and uploaded the wrong one here.
I do have a dried specimen that is a Mycena, and microscopic features with slightly amyloid spores. And it smelled like bleach. I would delete this observation and start another one but I need this for a mushroom class, if you can please view the new photo and vote it back to the correct species I’d appreciate it.

Thank you,


On M. alcalina

M. alcalina is a “name that has been rejected because of difficulties in interpreting it” [Trudell & Amiratti].

The caps are flat, which does not agree with the description and photos in A.H.Smith’s monograph (“evenly and obtusely conic […] sometimes convex or with a broad obtuse umbo”).

Perhaps this is not a Mycena.

typo – amyloid spores

Does M. alcalina have non-amyloid spores? need to check that… The photo also looks like Strobilurus.
