When: 2010-10-06

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

Who: Douglas Smith (douglas)

Specimen available

Found on a moss covered rotting log, in mixed forest.

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

The second micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are fusoid-ventricose to lageniform, half blunt, half sub-capitate. Pleurocystidia are uncertain, some obs. but rare, and usually need the gill edge, also gill were old and very full of spores. 4-spored basidia, spores with uncertain dextrinoid reaction, many with no reaction, some with a slightly brick-red reaction.

The third micro-shot of the stip apex at 400x in KOH. The caulocystidia are fusiod-ventricose, many with sub-capitate ends. Cystidia obs. at the apex and base of the stipe.

The forth micro-shot is of the spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, roughened, with a clear plage on most. Slightly small for a Galerina, with an apr. size of 8 × 5 um.

Putting this together I was confused for awhile. Back and forth, and it didn’t help things with the uncertain pleurocystidia. But it looks like the best id here is Galerina triscopa on these. Doesn’t help that this species seems to be rather vaguely described in the various texts, and there doesn’t seem to be many good photos of it anywhere…
