It was devilishly hard to get anything off that metal in decent shape. But I tried to make sure I didn’t grab any of the other species growing nearby on that junk piece. So it all should be one species (“Margin of error” is always there, of course). I wonder if observation 88242 might be the same species. It’s minute too – never grows to any significant size, and old benches in local parks are often covered with it.
But I have the specimen to prove it in front of me. You collected a variety of scraps from this thing. Some are pure white below, suggesting Physciella, but some pieces are large enough to see where the lower surface turns black several mm back from the margin. So, even though you can see white rhizines poking out from underneath in the close-up photos, I’m convinced that these are all Phaeophyscia not Physciella. All pieces were K- in the cortex. Then it’s just a matter of finding a piece with soralia on it. I couldn’t find any in the photos, but I’m looking at one right now that clearly has capitate soralia at the tips of tiny erect side-lobes. Nothing else it can be.
Nothing really spectacular to look at, just posted it since it’s growing on metal junk scattered in the woods.
