Wikipedia has this to say about the gills of this sp.:

The gills are ascending and somewhat hooked or toothed, narrow at first but becoming rather broad (2.5 mm and becoming 3–4 mm). They are nearly equal in width throughout or slightly ventricose in age, with a spacing that is close to subdistant. About 18–24 gills reach the stem, with two tiers of lamellulae (short gills that do not extend fully from the cap margin to the stem) that may develop veins running between them.

(emphasis added)

The source cited for that description is:

Smith AH. (1947). North American species of Mycena. Ann Arbor: University of Michigan Press. p.166–68

I would not, however, call these “slightly ventricose.”

Another reference:


calls the gills “dorsally intervenose with age.” The gills here appear to be broadly and abundantly intervenose at most stages of development.

Marasmioid vs. Mycenoid

In my experience, intervenose/anastomose gills is a much more mycenoid quality than a marasmioid one. One notable exception is Marasmius cladophyllus and Marasmiellus volvatus, of which this is neither. Mycena holoporphyra is a good example of this gill pattern in mycenoid fungi, as well as the Atheniella Sava proposed.

Another typically mycenoid quality is the translucentness of the cap and stem tissues, scalloped cap margin, and cap striations.

This was for certain Masasmius
So many proposed names, guess we need micro or something?
