Found under pine, spruce, oak, beech.

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

The second micro-shot is of the cap surface at 400x in Meltzer’s. THe cap is a cutis, without gelatin or pileocystidia.

The third micro-shot is of the stipe surface near the apex at 400x in KOH. The caulocystidia are also fusiod-ventricose with blunt ends. No caulocystidia at the stipe base.

The forth micro-shot is of spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, roughened, some with a plage. Apr. size is 9.5 × 6 um.

This all points rather easily to G. marginata.
