Lobaria pulmonaria
Tan, irregularly shaped growth. "In sexual reproduction, the species produces small reddish-brown discs known as apothecia containing asci, from which spores are forcibly released into the air (like ballistospores). Based on studies of ascospore germination, it has been suggested that L. pulmonaria spores use some mechanism to inhibit germination—the inhibition is lifted when the spores are grown in a synthetic growth medium containing an adsorbent like bovine serum albumin or α-cyclodextrin."

Thank you. I'll update the spotting :)
I believe those are the reproductive structures of the lichen.
