Found in moss and grass, under pine.
The first micro-shot is of the gill edge at 400x in Metlzer’s. The cheilocystidia are tibiiform, long thin, with capitate ends. No pleurocystidia were obs. The basidia are 4-spored and there are no reactions to the reagent in spores or tissues.
The second micro-shot is of the cap surface at 400x in Meltzer’s. The surface is a cutis with no gelatin, but with pileocystidia. The pileocystidia are cylindrical to tibiiform, small and thin.
The third micro-shot is of the stipe surface near the apex at 400x in KOH. Caulocystidia are obs. at the apex and base of the stipe, and are cylindrical to lageniform, with capitate ends. Also there are no clamp connections obs.
The fourth micro-shot is of the spores on the stipe at 1000x in KOH. The spores are ellipsoid, narrowing to the end, lightly punctate, with no plage nor germ pore. The apr. ave. size is 9.5 × 4.5 um.
This all points rather well to G. graminea, also known as G. laevis. I can’t seem to find enough info to decide which name is more appropriate. This is fairly similar to G. clavata, although it tends to be slighter, the spores are thinner, less pigmented, with a rather characteristic shape, and the cystidia are thinner. This all seems to be splitting hair perhaps between the species perhaps, but if you compare a few obs. between the two, the differences are consistent.
This is the most common, and very common, Galerina on moss in this area of France.
