This is clearly a Conocybe.

You should also take a look at the stipe surface to check caulocystidia a very important feature on determining to section level and eventually – with much luck;) – to species level. Also cheilocystidia are very very important. Galerina never have that prominent lecythiform ones.

Not all of the spores are aligned well enough…

but for some of them a germ pore may be seen. A few of them which are seen directly from the side appear truncate. Others show a little circle at the apex.

Unfortunately I can not make any details out in that shot to say if this is Conocybe or Galerina, but if its really cellular then Conocybe is a better choice. You might be able to make a better section if you make a very thin cross section of the cap apex, you can cut it at an angle and then cut off any parts of the section that is not as thin as can be. :)

Could you make out a germ pore in your spore photos? Galerina won’t have one, most Conocybe do, but not all.

(Conocybe ML NT 5-12 5)is a smash mount taken on a piece of cap. I think I got the cuticle separated from the gills. This photo appears to show a cellular structure, and the small number of spores seems to indicate that the material is not a piece of gill. I could find no filamentous material. So I think this makes a good case for Conocybe.

Also, according to Largent, Galerina is unlikely to occur on humus. The habitat for this collection was soil enriched with decayed wood from an apple tree.

Cap surface

You could probably distinguish the two genera easier by looking at the cap surface if all you have is 400×. Also, not all Galerina spores are roughened and some Conocybe spores are.

Thanks Rich, I’m leaning toward Conocybe.

Habitat doesn’t favor Galerina. My old 400x scope does not always reveal enough detail to determine spore ornamentation. I’ll evetually put either spores from a print or a gill slice under the scope. Hoping for a good read on the print color. Conocybe has that sorta red tint that’s pretty distinctive… if you get a thick enough print.

check the spores.
Conocybe spores will be smooth, while Galerina spores will be roughened.
this looks like a Conocybe to me.
