Observation 11681: Melanelia

When: 2008-09-29

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Brownish-green elevated lichen with white underside and white cracks on the top (note fresh-broken edge near top of photo). Leaflike, no rhizimes (hope I got that right, Jason) present. Reminiscent of the one of the stages that ferns go thru before they develope fronds.

Definitely Melanelia

I’m afraid this thing has got to have rhizines underneath it somewhere. I feel your pain. These things can sure appear to be white and bare underneath. You’ve essentially just got to wait till you find some healthy fully-mature specimens with lots of apothecia or isidia before you really see these species are supposed to look like.

I’m still going with Melanelia subaurifera for yours, but I still can’t tell from the photos for sure.
