Observation 114553: Peltigera neopolydactyla (Gyeln.) Gyeln.
When: 2012-10-24
No herbarium specimen

Notes: In regards to possible other lichens species at this site, have included 3 additional lichens, all found in the same sand dune area just south of Cape Lookout State Park, perhaps 5 miles distant from the park itself.

This lichen has a foliose gray-green surface; slightly upturned white areas that sometimes turn orange or orange-red. I cannot tell whether this is its typical color, or whether it is just starting to plump up from recent rainfall.

Color is pretty variable on Peltigera

The only color difference that really signifies anything is whether it is grass-green when wet (from containing green algae). Anything else means it contains cyanobacteria.

This is definitely not P. horizontalis group because the apothecia are sticking up. It looks quite shiny, so I think it has to be P. polydactylon group, of which it looks most like the broad, undulating, thin-leafed P. neopolydactyla.
