When: 2010-10-06

Collection location: Berliner Stadtforst, Berlin, Germany [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found in Sphagnum moss, under pine.

First micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are numerous on a non-fertile edge, lageniform with elongated necks, and blunt ends. Some kinda cylindrical with sub-capitate ends. Many with wavy walls. No pleurocystidia were obs. Basidia are 4-spored, and 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 caulocystidia at 400x in KOH. The are mostly cylidrical with blunt ends, many bent. Numerous at the apex, not obs. at the stipe base.

The forth micro-shot is of the spores from the stipe apex at 1000x in KOH. They are ellipsoid, smooth, tan, no plage, no germ pore. apr. 11 × 6 um in size.

Putting this together, it matches rather well with G. mniophila. This species is a Galerina from the growth with moss, and dextrinoid spores, but the spores are still smooth. It turns out the spores have a perispore but it doesn’t break up or show a plage (there might be one, but it could be hard to see with a light microscope).
