But in this region, Cryptothecia striata has the better odds. Up close it is unmistakable: it is very soft and fuzzy and thick. The “soredia” are a very weird consistency. There are some close-ups that really show it well in observation 61597.

The second photo,

can be Phlyctis argena (cf. MO68574).

Not many scripts I can guess by site

But this may be one. The white pruina has a very strong C+r reaction (bleach).

The second photo, as you suspected, is another species. It’s Cryptothecia striata. It supposedly has apothecia in there somewhere but they are, well, “cryptic” as the name would suggest! I’ve never noticed them myself.

Lichens of NA is a great book. Standard of excellence for it’s sort of thing. You will not be sorry. It will be of limited help in southern Florida, though. Look for the Fakahatchee Strand paper by Lücking et al. Some really exotic things down there.

I will pick up he NA lichen book this week so I can have a clue about lichen morphology, as of know I have none. In fact in these two images, I wouldnt know if they were two distinct entities or not. Look forward to using your info in a useful manner.
