Hey Jason,
There is a molecular phylogenetic work coming out on the Lobariaceae (Hognabba, in press), and an early version of it (the associated thesis) shows Pseudocyphellaria anthraspis (and P. anomala) outside of Pseudocyphellaria and closer to the type of Lobaria. Yikes! If this data holds up, it would call into question the utility of pseudocyphellae as a taxonomic character! I’ll be monitoring this situation very closely.
All the best, Brendan

It has dots on the lower surface

You can just make out the raised dots on the underside (the white surface even though it looks like it’s the upper surface on these photos) — that makes it a Pseudocyphellaria. The one with super-abundant apothecia like this one is P. anthraspis. Sticta also has dots below but they are craters, and there don’t seem to be any North American species with apothecia(?)
