Observation 13073: Lepraria Ach.

When: 2008-10-22

Collection location: Wayne National Forest, Athens Co., Ohio, USA [Click for map]

Who: Dan Molter (shroomydan)

No specimen available

Notes:
You know it’s been dry when shroomydan is reduced to photographing blue stains on rocks Haha!

Some kind of lichen is turning these boulders blue. You can see in the last photo that the individual thalli are smaller than the grains of sand composing the rock.

Recognized by sight: I call all bluish-grayish “leprose” lichens Lepraria (i.e. thallus is composed entirely of granules — no cortex, apothecia, rhizines, lobes or anything). Chances are very good this is even correct, at least Lepraria sensu lato. (Busy-bodies are of course dissecting the genus even as we speak.) But without access to a full chemistry lab, we don’t stand a chance of pinpointing the species.
