Observation 83512: Mycena sect. Fragilipedes (Fr.) Quél.
When: 2011-11-20
Herbarium specimen reported

Notes: Growing in humus, in a mixed forest (Tualatin Hills Nature Park).

No odor recorded.

Spores 8-9 × 5-6 microns, amyloid. Basidia 2-spored.

Cheilo- and pleuro-cystidia are large; the micrographs of them were taken using the 10x objective.

The mushroom does not key out easily. More microscopy is needed than what I did before drying the specimens. Need to measure those cystidia and learn more about the pileipellis (check if there is gelatinous matter there, and make sure the hyphae are smooth).

At the moment, of all descriptions that I tried to match, M. macrocystidiata (Smith’s book) seems the closest. M. algeriensis looks similar (picture in Robich’s book), but has larger spores (9-12 × 6-7).
