Congratulations on finding a new state record! Some states it’s easier than others… you happen to be in one of the best-collected states in the union! So good job!

Jim Bennett just identified this specimen as such, and he considers it a new state record. I know you were saying all along, Jason, that the species got to be here somewhere. And your hunch about this specimen was right too. You can pour yourself a drink :-)

Spot tests on soralia of Physconia are so difficult to read

I feel your frustration!

This one seems to be similar to observation 159640

Again, K+ yellowish in medula, lower tips of lobes whitish. Also, it seems to me that soralia change their color when K is applied. I can’s say if it becomes “dingy yellow” like in P.leucoleiptes, since soralia are “dirty” in color in first place, and I can’t describe what color they become (darker than they were).

Definitely Physconia

(Based on pruina, coarse marginal soredia, gestalt lobe shape.) Looks like P. enteroxantha, but colors are all off when wet, so hard to say.

Or isn’t ?
