#butterfly @bcwarwickshire.bsky.social Common Blue or Brown Argus? Markings don’t quite seem to be right for either.
Hummingbird hawkmoth, Small Copper, Red Admiral and Gatekeeper. Warwickshire garden and field edge #moth #butterfly
Though I have had a Micarea peliocarpa where I only saw the C red reaction in an apothecial section under the microscope
Interesting. I’m afraid I can’t add anything useful to Anthony’s points
Brown Argus in our Warwickshire garden on Bird’s-foot Trefoil
Interesting. I’ve only seen it non-fertile or with apothecia, but wondering whether yours maybe has pycnidia? Like Cladonia can have apothecia and/or pycnidia. The Italic website says Bunodophorum can have pycnidia, so seems plausible? italic.units.it/index.php?pr...
Bunodophoron melanocarpum (Sw.) Wedin
Thallus fruticose, shrubby-coralloid, 3-5 cm high, often forming extensive mats; branches highly divided in upper part, markedly flattened, especially towards the base, ending with small, subterete, p...

I really thought it was a map! Very nice.
I’ve a strong suspicion they are mites rather than slime mould. Mites like that (oribatid mites) are very common under or amongst lichen. I have seen quite a range of slime moulds (including Trichia), but none anything much like that. I think I can just about see tiny legs.
The soredia gave a faint pinkish reaction to K (not really ‘dull violet’).
#lichenGBI Caloplaca teicholyta with apothecia. First time I’ve seen it fertile. On calcareous ironstone, Warwickshire, UK. Used video to catch the red reaction on the apothecial section, as it dissolved out rapidly. The soredia gave a faint pinkish reaction to K (not really ‘dull violet’) >

So Labour say they won't install swift bricks because they are moving away from specific species mitigations to landscape level ones.

But swifts nest IN BUILDINGS. So how is landscape-level compensation supposed to help? Just ecologically illiterate nonsense 🤦‍♀️

Labour blocks proposal for ‘swift bricks’ in all new homes
MPs had previously backed Conservative amendment to ask developers to provide hollow bricks for endangered birds

Nice photos. Not one I know.

My first post! And my posts are going to be about lichens. Because they are amazing and I love them! This is Dimelaena oreina, moonglow lichen. A tiny sample highly magnified, from Ft Adams, RI
That is a fantastic display of slime mould (not a fungus or a lichen). It will likely change colour and texture dramatically. Not sure which one, maybe something like Didymium or Fuligo, or Brefeldia, but the PNW likely has different species to where I am in the UK.

🌿 Rainforest in the UK 😮
At the Chelsea Flower Show @RobStoneman, Director of Landscape Recovery at @TheWildlifeTrusts, is championing from the Rainforest Garden, which won silver-gilt. It is a breathtaking exhibit reminding us that rainforests are not just tropical.#ChelseaFlowerShow
Apothecium, plural apothecia. Like jam tarts. Some lichens have perithecia, which are enclosed. Both are types of lichen fruiting body, that produce the spores
Sequencing has its own deep rabbit-holes!
Agh! Sorry! Not sure I like the name variiformis anyway, it sounds like it has even worse implications than varia. Dastardly things
Interesting. The habitat description for A. variiformis maybe makes it less likely? (Mostly coastal.) Don’t think it’s a UK species, so I wasn’t aware of it before. But I agree these lirellate things are tough. I have several samples that need reviewing as I couldn’t decide what they were.
It looks like a lovely soft candlewick blanket. Perhaps Lepra (Pertusaria) corallina?
