#butterfly @bcwarwickshire.bsky.social Common Blue or Brown Argus? Markings don’t quite seem to be right for either.

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’) >

#eclipse projection just now onto paper, using binoculars, cardboard and (a lot of) parcel tape. Quite a fiddle to set up. Warwickshire, UK

#lichenGBI For comparison, something similar, but that doesn’t quite fit P. ucrainica, because it’s much too orange (but doesn’t quite fit anything else either, so recorded as P. candelaria s. lat.). From dog-wee zone, low down on calcareous ironstone. Found in 2 sites, same habitat. Warwickshire

#lichenGBI Another #lichenicolous fungus This one is supposedly mostly coastal, but was found 25 miles inland, on Xanthoria parietina, on a branch fallen from an Ash. Midsomer Norton, Somerset. Surprising spores with 3 septa in a black apothecium. britishlichensociety.org.uk/sites/defaul...

#lichenGBI Second time I’ve found the #lichenicolous #fungifriends Lichenochora galligena on Physcia adscendens. This time from North Somerset. On a fallen Ash twig in Midsomer Norton.

#lichenGBI #Lichenicolous #fungifriends Illosporium carneum. Noticed and identified by Neil Sanderson while identifying a mature Peltigera didactyla (without soredia) for me. From the track verge to an ex-sand/gravel pit nature reserve in Warwickshire.

Yes, colours vary so much, and descriptions can be very subjective. Pretty confident this one is Lecidella stigmatea though - much paler than the others, and the blue-green pigment only in the exciple, rather than right across the epithecium. (I have to think hard with the words exciple/epithecium.)

> But I’m not at all confident with Lecidella (or even sure it’s that genus). Had a good discussion about them on the other app if you still have access (part of thread in photos). Perhaps your spores might just be sub-mature, and so a bit small, if all still in asci?

I took this pair of photos of several Pertusarias a while back. (They may vary somewhat, this was just looking to see what would happen.) IDs checked by microscopy of spores etc.
Left, Pertusaria hymenea; top, Pertusaia coralliza; right, Pertusaria leioplaca maybe; bottom, Pertusaria pertusa

#lichenGBI Thank you @northernhills.bsky.social. I now think this is Lathagrium (Collema) fuscovirens (not L. auriforme)? Narrowish, branched lobes with small globose isidia. Lobes swell a bit in width, less than double (but lobe cross-sections swell to c 3x thickness). Gloucs. On concrete path.

Experience, mostly, having seen both Nostoc and jelly lichens (used to be Collema or Leptogium, but now lots of new names). Nostoc only has cyanobacterial chains and goo. Jelly lichens also have fungal hyphae, giving more form than ‘pure’ Nostoc. But they are more jelly-like than other lichens

I’m doubting myself now though! But these two photos were of a non-fertile Enchylium tenax. The original post looks a bit browner though. Jellies aren’t easy, but they are so attractively weird!

#lichenGBI Suggestions welcome. Whitish crust, patches to c. 2 cm, with warty (to sorediate?) centre. K-, C-, on lower trunk of a roadside Ash tree. Warwickshire.

#fungifriends A curiosity. Tiny fungal fruitbodies mixed in with Caloplaca citrina lichen on a damp calcareous wall. 60-160 um diameter black spheres containing 8-spored asci. Spores 1-septate, with 2-4 inclusions. Looks a bit like a powdery mildew, but think they are found on plants.

#lichenGBI New to me #lichenicolous fungus, on Phaeophyscia orbicularis: Arthonia phaeophysciae. On an Ash trunk by a roadside near home. Warwickshire UK. Lovely little light-bulb-shaped spores, and bulbous asci.
