Colour variation in Lecidella elaeochroma apothecia #lichen
Your photos are lovely - but would be even better with the species names added (please)!
Sorry, forgot to add its from Dorset

Unexpected on Larch twigs covered with Physcia tenella and Xanthoria parietina - a solitary Teloschistes chrysophthalmos! #lichen
Unfortunately most lichenicolous fungi need microscopic examination to check/measure the spores and conidia - and lots of the little black spots tun out to be invertebrate frass!
Just bought two of his books, partly for my oldest granddaughter who's very interested in both the Irish language and its roots and connections
Sorry, no microscopy - the photographs on the Dorset Lichens website were taken during a lichen meeting led by Neil Sanderson and I didn't collect a specimen

Houseboat deck on lignum, thallus +/- sorediate, K+yellow, C+ orange, UV+ orange-brown. Pale brown apothecia, some pruinose, spores 8-13(-15) x 4.5-5 µm. Possibly very fertile Lecanora expallens but KUV(wet)+yellowish instead of bright green?

Do you use raw or stick to jpegs for your images?
Call for the Battle of the Beanfield to be included in Orgreave policing inquiry - but as the Northumbria police conveniently destroyed the papers last April that related to Orgreave I doubt the Wiltshire police will be very forthcoming. www.theguardian.com/uk-news/2025...

Ah, that makes Circinaria calcarea (Aspicilia calcarea) more likely than contorta. I really should have learnt not to attempt these from a photograph by now!
I spent a couple of years trying to get to grips with bryophytes but gave up and returned (with relief) to lichens!
First question with these is what substrate was it on as that can be very relevant. Purely from the image I'd be considering Circinaria contorta (Aspicilia contorta subsp. contorta) rather than Circinaria hoffmanniana (Aspicilia contorta ssp. hoffmanniana) or Circinaria calcarea (Aspicilia calcarea)
In your website Lobarion Lichen Guide 1 it says
"Although common names have been used in this guide, few common names or lichens are universally accepted. Scientific names should always be used when recording lichens to avoid ambiguity".
Surely this shows that they DO need to be included?
I appreciate your aim is to interest people in lichens but omitting species names isn't helpful!
People can enjoy the photos but you deprive anyone wanting to know more of vital information. Even children manage dinosaur names so surely you could include the species names too?
Possibly Tall Tutsan, Hypericum x inodorum (H. androsaemum x hircinum)?
Oh then again that only applies if you're accessing posts with adult content, rather than for everyone!
Thanks Anthony - I've not got much further with this (distracted by Arthonia "phaeographidicola” on Phaeographis) but on balance most likely to be Lecania as none of the twigs collected were particularly acidic, and there was a lot of algae over many of them
Struggling to identify photobiont in this C- #lichenGBI on twig, not nutrient-enriched. Apothecia and spores fit both Lecania naegelii (C-, photobiont chlorococcoid, cells 6–16 μm) or Micarea peliocarpa (C± red, photobiont micareoid, cells 4-8 μm wide) @aspenecology.com @larkinlichen.bsky.social
I wonder what their next reply will be!
