Observation 62185: Galerina sideroides (Bull.) Kühner
When: 2010-11-06
Collection location: Bossy, Switzerland [Click for map]
Herbarium specimen reported

Notes: Found on small woody debris in mixed forest.

The first micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are small, thin, wavy, with part of them capitate. No pleurocystidia were obs. 4-spored basidia obs., and spores non-dextrinoid.

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

The third micro-shot is of the stipe apex at 400x in KOH. The caulocystidia are similar to the cheilocystidia, and some are branched. No caulocystidia obs. at the stipe base.

The forth micro-shot is of the spores from the stipe apex at 1000x in KOH. The spores are smooth, tan, ellipsoid, with no germ pore. The apr. size is 7 × 4 um.

Putting together, with the capitate thin cystidia, and the small smooth spores, and the viscid caps, this is fairly clearly Galerina sideroides.

It is interesting to note the macro details on these. The veil remnants on the cap surface, the off-white surface hyphae on the stipe, and how the stipe darkens from the base upwards, and no clear veil remnants on the stipe.
