Un-IDed lichens 2

[JennyS]

And some more .......

1. On top of harbour wall - Hyperphyscia adglutinata?




2. Top one on harbour wall, lower on upland rock - Lecanora muralis despite pale-bluish colour of apothecia?




3. On acidic coastal rock - Pertusaria?




4. Among moss near base of Alder trunk - Sticta?




5. Very small, on horizontal branch in woodland with plenty of oceanic Atlantic woodland species, Lobaria further along the branch




6. Just had to stick in couple more Caloplaca queries! They were next to each other on acidic coastal rock - two colour versions of the same species?

Hi Jenny

Obviously these are mostly things that require work - checking spores etc. - and difficult or maybe unwise to try to name from photographs.
In other words I cannot give you a complete list of answers - maybe just pointers.

1. I don't think this is Hyperphyscia, though it is one of that group. It is so wet that it is impossible to make out useful characters (other than that it is one that goes bright green when wet) - you have seen my views on photographing wet lichens already!
Why not Phaeophyscia orbicularis?

2.Yes, Lecanora muralis, also looking unusual because it is wet, though it does vary in apothecial colour.

3. Not sure. My first thought was immature Aspicilia contorta, but the acid rock argues against this. Maybe one of the Aspicilia cinerea aggregate? If so, then probably too young to ID.

4. Sticta fuliginosa seems probable, but I don't know these high Atlantic species yet (I am giving myself more time to learn common things before I venture into our equivalent regions in W. Scotland). Anyhow, it is too wet. The film of moisture makes it impossible to see the isidia clearly.

5. No comment.

6a. This might well be your most interesting find in this batch.
I wonder what it is?

6b. Not something I would ID from a photograph, but start with Caloplaca flavocitrina ...

Hi Alan, thanks for looking over this lot and my apologies for posting (yet again) photos that aren't good enough to make out vital details clearly enough. I think I need to delete a lot of the photos I've taken as they are making identification even harder than it already is

1. it was raining ......
I'd discounted Phaeophyscia orbicularis as there were only a few whitish rhizines, and because of the yellowish-green soralia.
Found the one below on a different rocky beach above HWM, bright green again even though it wasn't raining - I think the wet shiny effect could be partly due to the camera I was having to use at the time, but it does make it pretty impossible to see clearly.. ( yes I know, bad workman blaming tools...)



2. The first photo was taken in the rain, but the second was taken on a dry day

4. Same camera again, it was a dry specimen but I needed to use the flash ....

6a. Came across another like this on rocks at a different beach - I'm now very intrigued as to what it could be as I'd thought I was just not recognising a variation of something I should have been able to ID
