Probably Galerina…

Well, given that this has a Myceniod body form, and has brown spores, then strictly stated this is a Galerina. It looks like it might be from the section Myceniopsis. It would be good to see if the spores are dextrinoid in Meltzer’s, but probably not required. There are a number of these where the spores are actually smooth, but they still have a plage, the spores are covered with a perispore, except for an area above the apiculus. Usually for these the cheilocystidia are not capitate. The bad news is that this section has perhaps the largest variation and greatest number of described species, and it is hard to sort them out really.

I’ve looked at a species from California that has smooth spores with a plage, I’m not sure I’ve posted those photos from the scope, I should do that. I wasn’t able to be sure of a species on that one either. Galerina vexans was close, but it is hard to say.

Oh, wait, was this on wood or on moss? Mostly these are on moss.

This latest photo was taken at max magnification [100x/ 1. 25 – 160/0 .17 oil]. The spores appear to be smooth.

just water – brown spores

Hi Douglas,

My microscopy is not very sophisticated yet. I simply placed a small piece of gill tissue on the slide, added a drop of water and the glass cover, and then viewed with the objective labeled [ 40x/0.65 – 160/0 .17 ].

I’m using a low resolution video camera that came with the microscope. This photo is a screen-shot from an AVI taken with the video camera. Spore color is brown, but I can’t tell if the spores are ornamented or not.

Hmm… not sure.

Those spores are vaguely a Galerina-like shape, but I can’t tell from the photo if they are ornamented or not. Also I can’t tell what color they were, what was the reagent for the slide? Were the spores rather yellow-tan to light brown, or fairly clear?
