Yesterday I had a chance to walk along Lake Ripley in Litchfield with a couple of friends. Across the road on the north side of the lake is Ripley Cemetery.
There was quite a mix of gravestones in terms of age, material, and style, which made for some good lichen observing.
I think these orange lichens are Elegant Sunburst Lichens, Xanthoria elegans.
I'm really not sure what the black stuff is; it's not that uncommon to find on gravestones. I'm not even sure if it's a lichen. I suppose it could be algae or fungus. Or it could be the dried up or dead remains of any of the three.
I think the orange dots are Sidewalk Firedot Lichens, Caloplaca feracissima. I think the big crustose lichen in the middle is Golden Moonglow Lichen, Dimelaena oreina. It's color is more of sea green, that I can never capture adequately with a digital camera.
