Observation 61544: Galerina mniophila var. cephalotricha

When: 2010-10-06

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

Who: Douglas Smith (douglas)

Specimen available

Notes:
Found in Sphagnum moss, under pines.

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

The second micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are numerous on a non-fertile edge, lageniform with sub-captiate ends. No pleurocystidia were obs., 4-spored basidia, and the spores are dextrinoid.

The third micro-shot is of the stipe apex at 400x in KOH. The caulocystidia are cylindrical, some wavy, most with blunt ends, but some with sub-capitate ends. No cyst. obs. at the base of the stipe.

The forth micro-shot is of the spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, smooth, and only a few obs. with a plage. Apr. size is 11 × 6 um.

Putting this together gives you a Galerina in the section Mycenopsis just fine, and it is a little confused with some authors from there. But Haan and Waylen described this very well as a variation of G. mniophila with shorter sub-capitate cystidia.

I found these rather common, in groups in the sphagnum under pines in this forest near Berlin. And I also found the other variation of G. mniophila (posted recently, http://mushroomobserver.org/61360) in the same area, also in groups. But I was able to keep them separated in the field, where this variation was rather grey, with randomly lightly wavy conical caps. The other variation has more yellow-tan hemispherical caps. But finding them common enough in the same habitat on the same day, makes me wonder if they are really two species, the same, or a variation…
