Observation 61546: Galerina atkinsoniana var. atkinsoniana
When: 2010-10-06
Herbarium specimen reported

Notes: Found in Sphagnum moss under pines.

The first micro-shot is of the cap surface at 400x in Meltzer’s. The cap surface is a cutis, without gelatin, pileocystidia were obs., but not numerous.

The second micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are numerous on a non-fertile edge, fusoid-ventricose with blunt ends. Pleurocystidia were also obs., 2-spored basidia, and spores dextrinoid.

The third micro-shot is of the stipe apex at 400x in KOH. The caulocystidia are similiar to other cystidia, and were obs. from the apex to the base.

The forth micro-shot is of the spores from the stipe apex at 1000x in KOH. The spores are roughened, pointed, ellipsoid, with a clear plage obs. on most. Apr. size is 12 × 7.5 um.

Putting this together, with most authors, and the pileocystidia, you get Galerina atkinsoniana var. atkinsoniana.

These were fairly easy to tell in the field as of the section Galerina, with the strictly conical caps, and the long smooth stipes in moss. To get the G. atkinsoniana id though needed the scope to see the pileocystidia.
