The black

seems to be dwarf fruiticose filimentous lichen in Brodo. The white I’d hazard are a crustose sterile lichen. There appears to be two different small ropey (thread?) lichens in the bottom half of the photo on the right-hand side. These are only visible when photo is on maximum enlargement. Maybe Ramalia?

I don’t see the the “cotton string attached to a small nail” – what part of the photo is that?

Good question. I thought the widely distributed white stuff to be crust fungi until I took some closeup photos. The black stuff is most apparent due to removal of bark scales by me and probably is fungi. (Moral: take picture first, take samples second) I had not noticed it but will add it to my DNA run. I don’t know what stringy stuff you are mentioning. One photo would appear to have a piece of cotton string attached to a small nail – is that it?

lichen are you referencing here, Martin? The black, the white or the stringy white?
