Photo #1 clearly shows rhizines, but they don’t appear to be black. “Lichens of Wisconsin” places Physconia perisidiosa at the far north of the state (Canadian Zone), while the specimen was found in the far south, although the south has pockets of the northern zone ecosystems (Governor Dodge park has one of them).
