Spore size

Douglas, thanks for your ID attempt. G. clavata is not rare here, but this didn’t look like it to me. I posted another photo that was not taken in the sun, just in case.

I believe that most basidia are 4-spored and am pretty sure that I’ve seen some 2-spored too. As for the spore size, my measurements might be wrong. The reticle in the eyepiece of my heavily used AmScope got loose and I noticed recently some unusually large spores in my recent Mycena work. I’ll try to borrow a calibration slide soon (and get a new eyepiece) to check this. Till then, I suppose we should not trust these numbers.

Here are 10 spore sizes from a new mount (squashed gill) that I just made:

14 7
15 7.5
13 6.5
14 6.5
12 6.5
12 7
12 6
11.5 5
13 7
11 5

The photos look a-typical, I would question those photos if this was really a Galerina, but it could be. But the micro-details are good. Yes, looks like a Galerina in sec. Tubariopsis. But the spore size is kinda interesting. Could you post the ave. and std. on the spore sizes, instead of a range? I don’t know what to do with a range. But the common Tubariopsis up and down the cost seems to be G. semilanceata. But that one consistently has a spore size about 9-10 um on ave., and without too much spread in the stnd. This one is larger. It would be nice to know, are most of the basidia 2-spored, or 4-spored? So, this one could be an honest G. clavata which is more rare, but I believe is out there. Could also be a G. subclavata, except that one should have even bigger spores. But also that one have a very large spread in the stnd. of the spore size, and mostly 2-spored basidia.
