Re: Chaenotheca: a Pd/UV Reaction & a Question

Remarkably, I still have the draft ms for the Saltburn Gill study and it includes data on wind direction from a weather station in nearby Saltburn town. By far the most frequent wind direction is SW, which means most of the pollution from Teesside is blown out over the North Sea (sorry Norway). West...

Re: Chaenotheca: a Pd/UV Reaction & a Question

Hi Neil: Sorry, can’t help with your sterile crust but glad you enjoyed Kilton Beck. I learnt my lichenology in that area back in the 1980’s when I was living in nearby Brotton. I visited Kilton Beck a few times, but was actually rather disappointed with it compared with some of the other ravines in...

Re: Dipping my toe into montane crusts - Porpidia and Lithographa

I have some pretty big chunks of mountain in my collection, but it's true that the most interesting-looking specimens always appear to be in the middle of a flat rock surface. It's always worth venturing into the hills when they're covered with snow - you tend to look at different surfaces (underhan...

Re: Dipping my toe into montane crusts - Porpidia and Lithographa

Hi Dave: Welcome to the wonderful world of saxicolous crusts – and thanks for the kind words about my thesis! I’m pleased that you found Lithographa tesserata first. It’s such a beautiful, unmistakable species that it’s the kind of thing to get you well and truly hooked! If you had gone straight int...

Re: Lichen ID help please - Lecidea lithophila ?

Hi Mark: Nice pics! Definitely a Lecidea sp. and L. lithophila is a very good shout. However, the apothecia in that species are usually brown - especially when wet - because of the brown epihymenium. I would tend towards L. lapicida - which has a blue-green epihymenium - but it is really impossible ...

Thanks for posting the directions! I wasn't aware of the problem at the time - I get a different screen because I'm logged in as me (obviously)!

PhD Thesis -Alan Fryday

After more than 20 years, my PhD dissertation (Ecology and taxonomy of montane lichens in the British Isles) has finally been scanned by the British Library, with financial assistance from the British Lichen Society. The two volumes can be downloaded from my ResearchGate site: https://www.researchga...

Re: Stumped, or sleepered

Neil:
I'm not convinced. The spores are the wrong shape (too narrow) for B. ocellata - not to mention not pigmented - and B. ocellata has a dark hypothecium and a much reduced exciple. I don't have a better suggestion, mind.

Re: Lecanora hybocarpa an overlooked lichen

Neil:
You should get in touch with Christian Printzen. He has a project 'Leconomics" <https://lecanomics.org/data/index.php?lang=en> investigating taxon delimitation in Lecanora. I'm sure he'd love to sequence some of your collections.
