Observation 9222: Galerina hypnorum (Schrank) Kühner
When: 2008-08-09
Herbarium specimen reported

Notes: A number of these found on moss on a conifer log.

9/2/2008 – Looking at them under the scope -

First micro-shot is of the gill edge at 400x in Meltzer’s. This displays the cheilocystidia, which are fusoid-ventricose with blunt ends, also that the spores are dextrinoid.

The next two shots are of the spores from the stipe apex in KOX at 1000×. Here the spores are ellipsoid, pointed, roughened, with a plage. The first one is like most of the spores in that it is roughened, with a non-calyptrate perispore. The second was an unusual spore that does show the perispore loosening from the plage and is slightly calyptrate.

Along with these details, also it was seen that the cap surface was a cutis, with no gelatin or pileucystidia. Caulocysitidia were obs. in clusters at the stipe apex, no caulocysitidia at the stipe base, but the base was covered with loose hyphae with hyphal tips, perhaps from veil tissue.

These details match well with Galerina hypnorum from the Smith and Singer monograph of North American Species of Galerina. (Although not from European sources for G. hypnorum, see notes for species.)
