Observation 61863: Galerina marginata (Batsch) Kühner
When: 2010-10-02
Herbarium specimen reported

Notes: Found on rotting wood, under spruce, beech, alder.

The first micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are fusiod-ventricose, with acute apecies. Pleurocystidia were obs. and are similar. Also the basidia are 4-spored, and the spores are dextrinoid.

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

The third micro-shot is of the stipe surface at 400x in KOH. The caulocystia are obs. at the stipe apex, and are similar to the cheilocystidia, no cystidia are obs. at the stipe base. Also clamp connections were obs.

The forth micro-shot is of spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, roughened, many with a plage, a slight narrowing of the end, almost to a thin germ pore. The apr. ave. size is 9 × 6 um.

This all points to G. marginata, which is laking the gelatin at the cap surface. A fairly common guy in Europe.
