Observation 81386: Mycena rubromarginata var. bulbosostipitata Hadjist. & Grund
When: 2011-10-30
Herbarium specimen reported

Notes: On a fallen branch (hemlock or Douglas fir).

Spores 8-10 × 6-6.5 microns. Couldn’t check whether amyloid or not.

Gills marginate.

[12 June 2016]

Spores 9-11 × 5-7. Cheilocystidia 29-47 × 10-16. The microscopy agrees with M. rubromarginata, though the mushrooms, with their convex caps and short bulbous stems look unusual. However, there is a variety bulbosostipitosa, described from Nova Scotia, that seems to have these features. Maas Geesteranus thought the published microscopy of it insufficient and that it “seems in need of more detailed reexamination before […] accepting”.

Marasmiellus, although the spores do not match with any species that I know.
