Observations I deem as important will get micro, I know they are all important, but i just dont have the time, I will scope as much as I can, and all active species will get scoped, as well as all Pans, and all Deconica.

Excellent observation. Good job capturing the caulocystidia.

I did, but it was on my photo file name.

So you couldnt see it. I updated it, sorry bout that. im slowly getting down the etiquette of micro…

Nice micro

But can you please label your micro pictures? Name of the cell/location of the section, magnification, and mount are are essential information. In this case only the spores in image 339986 looks any bit roughened to me, but you said melzers made the spores smooth so which pics are mounted in what? :)

soon yes.

Or is this going to be just another not so useful Panaeolus observation with pretty pictures? :)
