When: 2008-09-16
Herbarium specimen reported

Notes: Found on moss on the ground, under oaks and mixed hardwoods. Very thin and small, lighter brown colors.

10/2/2008 – Getting this one under the scope —

The first micro-shot here is of a gill edge at 400x in Meltzer’s. Here the cheilocystidia can be seen, and they are fusoid-ventricose and capitate. Also the spores are clearly dextrinoid. There were no pleurocystidia observered.

The second micro-shot is of caulocystidia at the stipe apex at 400x in KOH. Here the cystidia are mostly cylindrical, and only a few rarely are sub-capitate. Also cystidia were observed the whole length of the stipe.

The third micro-shot is of spores from the stipe apex in KOH at 1000×. Here the spores are “calyptrate” (I like the term “skirted”), where the perispore has loosened from the spore surface, and this produces “ears” near the plage area. The spores are also pointed, inequal in profile, and almost sub-rhomboid in face view, slightly like Psilocybe spores.

Putting this together with checking that the cap surface is a cutis (it was), to make sure it really is a Galerina, and the fact that no trace of a veil was seen, the id comes out as G. subcerina. This was true using Smith and Singer, and Watling and Gregory.
