Observation 11637: Lichen P. Micheli
When: 2008-09-27
No herbarium specimen

Notes: Lichen growing on my Quercus palustra, a gift from a local squirrel. This lichen is the one in the center of the photo: grayish-green with tiny erumpent cup-shaped fruiting structures (at least I think they’re fruiting structures). Lichen is a very thin crust over the bark of the tree, fruiting thingies are prhaps 1-2mm above the background; total width of the lichen is 1.5 inches.

Unless it is a particularly recognizable crustose lichen, you almost have to look at the spores to get anywhere. The lovely, thick, smooth rims on the apothecia are very enticing, suggesting maybe Ochrolechia.
