Observation 81852: Mycena quinaultensis Kauffman
When: 2011-11-05
Herbarium specimen reported

Notes: Growing on a moss-covered conifer log.

Stem and cap both viscid. Stem up to 5mm thick.

Has odor that I cannot describe. :(

Spores 6.5-8 × 4 microns; coundn’t check if amyloid.

Basidia 4-spored.

Large smooth cystidia, observed on a crush mount.


Reexamined 20 March 2013

Even though it was found on a log, this mushroom is a humus-dweller (first photo).

Spores 8-10 × 4-5. Basidia 4-spored, ~30+5 x 7. Cheilocystidia ~85 × 15, not forming a contiguous layer. Pleurocystidia ~45 × 12.5.

Gelatinous layer on stipe prominent on one slide, totally absent on another (different specimens used). There’s been some controversy about this in the literature.

Cells with enlarged ends (often irregular) were typical in the pileipellis. I’m not seeing this mentioned in the descriptions.
