Lichen dabbler and photographer, Anapana-practitioner, sky watcher. I'm really here for the #lichens, but keep getting distracted by the wonderful #landscapephotography

And in an age of war and inhumanity, extremism and violence, I repost other things too
Oh excellent. They must be quite common where you are.

Oh amazing. Three fruiting bodies together. And I think I can just see a bit of the dark green thallus, the ‘body’ of the lichen on the surface of the peat. If you can it’s good to get thallus and ‘umbrella’ together.😋

Well worth it though for this image of the fruiting body. You were right down in the bog for that one!

Like an octopus with all those “suckers” on its many “arms”. Must be a Ramalina of some kind.

Hi Eric. That's a good picture. Physcia adscendens, no doubt. Yes, they are tiny. You're becoming very observant, that's great.

And, yes, those little black dots do look like pycnidia. If it's what I think it is, this species is common on well-lit calcareous rock – or concrete! You say the lobes had burst open and revealed the insides. What shape were those open lobes, and what did you see inside them?

An amazing array of overlooked wonder, just on an ordinary everyday curb stone.
Do you know what genus the long pale lobes with the two-tone cilia belongs to?
I see a Xanthoria at bottom left. I also see some more orange-tinted apothecia. Possibly one of the genera that used to be in Caloplaca.

Jenny, what part of the country was this in? It seems like a great find.

Very helpful, thank you for the link

Welcome Nathan,
Come and let us see your latest #lichen finds. You may like to use the hashtag #lichenGBI.

Wow! You must live in an amazing lichen area. No wonder you’ve become so interested in them.
October 9, 2025 at 12:41 PM
A Physcia, an early coloniser so one that is often found on young twigs.
October 8, 2025 at 8:21 AM
OK, that's great. Definitely a Ramalina as you say, and you've found which species are likely in your area. So let's work on the description. What are you seeing here? Your last description of a lichen was great, so can you use "lichen language" to explain what you see here?
October 6, 2025 at 11:01 AM
I think the genus is no big problem.
Narrowing that down to species level is another matter. It probably isn’t a species I’ve ever seen, and also I have no idea which species grow in your area.
Are you able to identify the genus?
October 5, 2025 at 8:42 AM
Wonderful, even it is a sign of nitrogen enrichment of the environment. Looks like Xanthoria parietina, though I am hesitant to ID southern hemisphere lichens.
October 1, 2025 at 1:39 PM
And something else, keeping the perlatum at bay. It’s war between neighbouring lichens!
September 30, 2025 at 8:46 PM
More P perlatum, and perhaps a Lecanora
September 30, 2025 at 8:44 PM
But it’s the short black marginal cilia which nails the ID. 2/2
September 30, 2025 at 8:40 PM
Hi!
That’s a very good description, and a good photo. Well done.
And both of those fit Parmolina perlatum. It’s one you may find quite commonly on trees.
I didn’t know it had any use in Indian cuisine, but there you go!
The way the soredia deforms the edges of the lobes is one visual clue 1/2
