my feelings about this genus. But, yes: I will play it again!

Sounds like golf…

Makes you mad and desperate, cursing the game, swearing you’ll never play again, but you do.

this genus is far from my knowledge and sometimes make me mad and desperate. Fortunately, you are here to correct our nonsense classifications.

Fertile P. collina

This can be a tricky species. I’ve collected specimens on tree limbs with abundant apothecia and no soredia, absolutely certain it was P. neckeri — what else could it be right?? — but no. Trevor Goward claims there is a difference in the veins or rhizines between completely-fertile P. collina and P. neckeri (but he hasn’t shared the secret with me yet!) Apparently material growing on trees is always P. collina regardless of whether it has soredia or not(!) Specimens like yours with both apothecia and soredia are even rarer, but they do occur (obviously!)

How nice …

to have a fertile specimen of an usually non-fertile species, with those violet/black apothecia.
Thanks, Jason, for one more help.
