we had a similar debate over macromorph characters of Gomphidius at the FFSC Fair. Guess that we should have just stuck some spores under the scope, for a more definitive analysis.

So Alan, the microscope man,

is choosing to ignore the microscopic evidence?!?

What you say is also true

and perhaps truer.
I admit that I totally missed that. I’ll lower my confidence vote, but I also would love to understand the morphological variation in these species better…

but aren’t the distinctly larger spores of G. glutinosus the distinguishing feature the separates the two species? G. oregonensis spores are always listed as being in the 10-14 micron range.
