Awesome, thank-you! Also your website is fantastic – super helpful
Cheers, I’ll try get some. I’ve just done another KUV test with much more K and it looks to be KUV+ yellow. Megalaria pulverea looks like a better fit then!
Many thanks,
Kian
Hi Neil, I don’t have any Pd so can’t test that. Heres a pciture that my friend took when i collected the sample. It’s also worth noting that green crust below is Miacrea xanthonica with a UV+ deep orange and persistent C+ orange test.
Cheers Paul, that looks like a better fit.
Many thanks,Kian
Nice I had some at Low Force in County Durham too in August. Definitely not common but fairly widespread! I saw your nice page on the BLS. Looks great!
Cheers, Neil. That looks like a pretty good suggestion! I’ll try and get a bit more under the scope and check the spores measurements and red core. I hadn’t even considered that it is likely to be a different kind of pin. Hopeflly it’ll all match and we’ll have at least one tree back in Yorkshire with this species! Many thanks and all the best,
Kian
Yh the first record is the main tree where there was lots mixed with Pyrrhospora quernea, Cliostomum griffithii, Pertusaria coccodes and Dendrographa decolorans. Just to check are you saying that the first record is correct but the L sublivescens is mixed with something else or that is not Lecanora sublivescens and is instead some other Lecanora? Many many thanks,
Kian
Hi Neil, I have some more Lecanora sublivescens for you, this time from Duncombe Park, North York Moors. I just want to confirm that I’m on the right track if that’s OK? These ones have a much more areolate crust. I counted it on three trees (all oak), two with only one or two small thalli and one with perhaps enough to cover a couple of A4 sheets. We’re hoping to go back at some point soon and check the rest of the parkland as we had some other nice species too (Psammina stipitata, Bellicidia incompta, Anisomeridium ranunnculosporum, Xylographa parella, Chaenothecopsis nigra etc.)

I think one of the perithecia was like that with an elonagted opening so that seems like a sensible suggestion, having done a bit of digging this Easter I managed to find this paper that was an overview of many species of the group (

Hi Paul, thanks for taking a look. I was supposed to add some macro photos today but have been at a conference all day, the perithecia are circular, I think the ostiole is central but its quite hard to tell, they don’t seem to lirellate, I’ve attached some pictures, the spores com from the large black round perithecia. Cheers,
Kian
Cheers Neil, That was the couplet I was struggling with! I wasn’t sure on the spectrum is the cutoff, so that’s helpful to know. I think your right that the ones on mine are bark cracks instead. We’ll have to see if we can find some more of it in Yorkshire, it has to be at least somewhere else! And thats annoying about the next batch of name changes, lets hope Lecnoraceae settle down sometime soon.
Many thanks,
Kian
Hi Neil, Much appreciated those are some handy tips, especially knowing that the colour isn’t reliable for corticolous ones. I’ll update my records now.
Kian
Thank-you so much for taking a look, I’ll bring it along to the AGM then. Julie Hilligsøe Lisby said that they see it reasonably often on trees in Denmark and has confirmed it on iNaturalist too. Kian
Hi Neil, I’ve tested it this morning and I’m pleased to say that it is KUV- (wet) and KUV+ (dry) bright yellow, as well as K+ lemon yellow overall and UV- overall. So I’m thinking it probably Palicella filamentosa? I’ll be at the AGM in Carlisle so can bring it if people want to look/ anyone would like the specimen for their reference collection?
Best wishes,
Kian
October 21, 2025 at 11:43 pm in reply to: Orange dusted pyncidia on Oak Bark, Buck’s Mills, Devon #46671Hi Gerault, I think you’re right with that, it might be a very strong K reaction which is reacting with the small amount of K in my C mixture (Milton Sterilising Fluid).
I went back to the site a few weeks ago and had a look for more of it. The chemical tests came up the same. The pycnidia “lichen” were abundant on a tree with a large amount of Alyxoria ochrolechia and are a similar colour to the pruina under UV. I wondered if it might be an odd form of Alyxoria ochrolechia with very few apothecia, abundant pycnidia and large quantities of pruina staining the thallus orange. The orange pycnidia patches do seem to grade into normal looking A. ochrolechia.
