Lots of these growing on this tree
not sure I'm in the right neighborhood
This crustose lichen was seen in a firmly adnate state on a large native stone. The microhabitat is oak savanna.
This open structure fruticose lichen measures about three cm across. The branches are very fine and quite flattened, with the terminal branches being extremely fine. The specimen was growing on a small Quercus kelloggii lateral limb.
This foliose lichen specimen measured about four by seven cm. Although adnate and with firm leathery texture, the terminal irregular lobes are only loosely adnate. The specimen was found attached to a piece of decaying oak bark on the forest floor, within a closed canopy element of the mixed oak-bay woodland here.
