Observation 82700: Mycena sect. Filipedes (Fr.) Quél.

When: 2011-11-11

Collection location: Hillsboro, Washington Co., Oregon, USA [Click for map]

Who: Sava Krstic (sava)

Specimen available

Growing on a fallen branch of a deciduous (?) tree.

Odor strong alcaline five days in the fridge; didn’t make a note of odor at collection time.

Basidia both 4-spored and 2-spored (unless I misinterpreded the latter). Typical spores 7-8 × 4 microns. No pleurocystidia observed.

The key in Maas Geesteranus leads to section Filipedes, but none of the species there seems to be a perfect match. M. arcangeliana does not have caulocystidia and has pleurocystidia. M. filopes would be OK with respect to cystidia, but its gills are more widely spaced, and its spores are larger. Both of these have a smell of iodoform, while what I have here is a tipical “alcaline” Mycena smell (again, unless I got it wrong).
