Some comments: I think you mean ixocutis? All of these I’ve seen so far in California have an ixocutis, which in the strict sense makes them G. autumnalis, but G. marginata is probably a fine name if you wish to use it. The cystidia are not clavate. Clavate mean wider at the end then at the source, like with basidia. In Galerina studies people call these fusiod-ventricose, which are rather thick at the base, and taper more or less evenly to the end. The ends here are blunt, and some are somewhat clubbed, which is a good feature for these. To get the gold star though you need to show the pleurocystidia… The spores look good, the right size, and rather rounded at the end.

Nice stuff, looks good with the Congo Red.
