Observation 164810: Verrucaria marmorea (Scop.) Arnold
When: 2014-04-19
No herbarium specimen

Notes: I don’t even know if this is lichen! I photographed it on a rock, presumably limestone, at Blevins Gap Land Trust Preserve, Huntsville, Alabama. Rich woods, very rocky, fairly moist.

it is possible to see some round pits on the stone. Thus I infer that this could be an old thallus of Verrucaria marmorea, due to the colour.

….it was rock, limestone as far as I can tell. Around here it is easy, it is either limestone or sandstone. Usually limestone.

If this were bark, I’d say Arthonia cinnabarina… but I don’t what it could be if it’s on rock.
