Your explanation was very helpful. Thank you, Jason.
You’re right, there are several species here, including a second Peltigera, even (the jade-green thing on the left side of the photo — P. apthosa maybe?). The one I was interested in for this observation (because it was so unusual) was the shiny brownish-grayish-greenish frilly thing growing on top of the moss in the center of the photo. P. collina normally has the granulose margins which you can see on this one (they look pale gray on this wet specimen), but this one also has those rich chestnut-brown apothecia (I count five in this photo). The black pimples on the rock on the right belong to a totally different lichen. (I’ve never had the time to collect and identify it, so I have no idea what it is! I finally got a specimen last month, but haven’t looked at it yet.)
Looking at the image I see 2, possibly 3 different lichens. I am a complete rookie – can you help me out?
Trevor Goward says that P. collina is either fertile or sorediate; he’s never seen it do both. Also, collina is in the P. neckeri group, so it should have pitch black apothecia. We have no idea what this is.
He says that fertile collina can be difficult to distinguish from neckeri. (Habitat is very different, collina preferring wet/dark forests, neckeri dry bright areas.)
