That part of the notes you've added to your identification could be a bit misleading.

Parmelia sulcata: The white reticulation can often form a +/- continuous network of lines on the thallus and the lobe ends are often brownish.

Punctelia species have distinctive raised white sorediate spots (pseudocyphellae) on the lobes.
