HINDS & HINDS mentioned that Leproloma was incorrect name, that was replaced by Lepraria in 2004

Curtis J. Hansen, Curator The Freeman Herbarium (AUA) also consider L.membranaceum as possible

By god, I think you’ve got it!

Looks spot-on. But Brodo’s comments about it being a “character-poor” genus probably precludes the possibility of us ever actually being sure! :)

Could be Leproloma membranaceum (Brodo p.399 pic.448)

all thalli look the same with this bluish tint. I am visiting the place several time each year will look again. This time I took people on a hike and while they made pictures of the furnace I made several pictures of lichens from the stone wall.

That’s thinking outside the box!

crust on top of Coccocarpia ???

Could this be a crust growing on top of Coccocarpia palmicola, along the lines of Daryl’s Observation #45053. If so, it did an exceedingly thorough job of using nearly all of the available real estate, but missed a few slender spots near the bottom of the photo.

here is a vebsite with a pictire including the wall around the furnaces. It’s sure not concrete.


No clue.

I asked around, and the “experts” are stumped, too. Granted Alabama is far from British Columbia…

C. palmicola?

It was several thalli @2"-4" on the wall with northern exposure. I found C. palmicola nearby, but in more natural habitat in shade on a mossy rock.

Could this be Coccocarpia palmicola?? I don’t remember the surface being so cottony. Maybe it’s some sort of Lepraria?? They do occasionally form well-defined lobes like that… hmmm, but not the grey tomentum below though.

Concrete and cement behave just like limestone as far as lichens are concerned. A good place to look for Collema, for example.
