Putting this under the scope —

The first microshot is of the gill edge at 400x in Meltzer’s. Here cheilocystidia can be seen on a non-fertile gill edge. The cystidia are fusoid-ventricose with blunt apecies. Pleurocystidia were observed on the gill face, although these were not numerous, there were many section of gill face lacking cystidia. The spores here are dextrinoid.

The second microshot is of spores from the veil tissue at 1000x in KOH. Here the spores are ellipsoid with pointed apecies, roughened, with a clear plage on most. The apex of the spores have a thinning spot in the cell wall. The spores are apr. 8-10 um long.

Also clamp connections were obs., and the pileipellis is a cutis, lacking any gelatin.

Need to go through the book better now, this is obviously a Galerina and somewhere close to G. marginata. It doesn’t agree with the form G. autumnalis that I’ve seen in California, the cystidia are lacking the clubbed ends that those show. These might be G. marginata in the strict form, which I haven’t seen in California yet.
