I guess this is L. heteromela, but check out those squarrose rhizines. Is that normal?
Coyotebrush can really come alive with a little water. There much more than just the Parmotrema here, of course.
Apologies for the bad pic. This was the only somewhat dry specimen I photographed, and it wasn't quite as compelling as the wet ones, but it matches the pic in Brodo quite well, while the wet ones don't really look like much of anything. Sharnoff has a number of his typically excellent pics, but they all look a bit dry: www.sharnoffphotos.com/lichensD/leptogium_milligranum.html.
Once again I need to expand my concept of this lichen's habitat.
New genus for me, and another cyanolichen! Apothecia on the bottom: wild.
Saw this on the PCT and don't know what it is..
I'm not really sure what I'm looking at here. It's a tripartate lichen but it has huge black spots that look to be cyano-bacteria, maybe the cyano-bacteria escaped but it looks lke they are living in strange giant cephalodia. The orange under the edges screams of peltigera and it's apothecia but I've never seen peltigera where the apothecia lined the entire under surface rather than stick up in lobes. I'll have to try to look up this lichen I think it's one I've never seen before. I saw this in the Jefferson wilderness at about 4,000 feet in elevation.
It looks a like a large Peltigera Venosa but with an orange under surface..
