Observation 61862: Galerina triscopa (Fr.) Kühner
When: 2010-10-02
Herbarium specimen reported

Notes: Found on moss-covered rotting wood, under pines and alder.

First micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are short, fusiod-ventricose, half sub-capitate, half with blunt ends. Pleurocystidia are uncertain, some seen but mostly near gill edges, most places on the gill face none seen. Also 4-spored basidia, and dextrinoid spores.

The second micro-shot is of the cap surface at 400x in Meltzer’s. The cap surface is a cutis, with no gelatin and no pileocystidia.

The third micro-shot is of the stipe apex at 400x in KOH. Caulocystidia are cylindrical to filiform, with blunt ends, and were seen at the apex and base.

The forth micro-shot is of spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, pointed, roughened, with a clear plage. Apr. size 8 × 4.5 um.

This all seems to point to Galerina triscopa, except that species isn’t really all that clearly described, and the uncertain pleurocystidia is quite annoying.
