Notes: Extensive to rather tiny custose lichen on Quercus palustra. In taking photos today I notice that deciduous trees in my area have far more lichens and lichen varieties than the conifers, which I didn’t find a single lichen on. This lichen was probably the most extensive. Some growths were up to 5 feet tall, and perhaps 1 foot across. Others were tiny, less than 2 inches across, but still rather large for most of the lichens I photographed today.

Five feet by one foot?? Cool! Definitely stick this one under your fancy scope and post some photos. (Get out the knife if you have to — your tree will heal — it’s all in the name of Science!) I’d love to know what kind of lichen is that aggressive.
I’ll bet nine-to-one the color differences are an artifact of automatic-color-balancing on the camera. They do the best they can, but they don’t always get it right! I’d be surprised to find multiple species with such an aggressive growth habit in the same place. But, yes, while color can vary tremendously in many lichens, I would tend to agree in this case that cream
vs bluish-white would indicate different species. Especially since there is no variation within a given specimen.
While not as noticeable when just viewing the photos on my computer, once they are in close proximity to each other on mushroom observer, it is easy to see there are different colors involved here. The top is bluish, one is cream-colored, one is white. Please let me know if this just observed color difference indicates different species as well. Newbie to lichens, here.
