as you labeled it. I understand, sometimes in the field we have our own objectives and target species that is easy to neglect the attention that some other species deserve. After all we cannot do everything, but those days you did a lot. Congratulations, again.

I probably tasted it, but I can rarely detect the bitter taste in the field. I was in a bit of a rush on that day, so I was only concentrating on certain groups and things that looked “unusual”. But this was so photogenic that I took it anyway. Certainly, the species is very common and well-known in the area, and other specimens I have from the Smokies which I have verified chemically look identical. So I think it’s worthwhile posting the photo despite the ultimate uncertainty.

Congratulations, Jason.

Tremendous set of observations you posted today.
Concerning this one, I felt strange the confidence level. Didn’t you taste it or made the spot test?
