These differences in morphology are certainly linked to the characteristics of the substrate and in particular to the ease with which the fungal prothallus can extend across the smooth surface. I have good examples of Rinodina aspersa behaving like this too

Look out for local differences in the colour of this lichen. It can cover quite a big area so you’ll spot it pale beige, dull green or red brown and with a slightly waxy sheen. Loves shady trunks

Often found in the south-west too on north facing walls and in mosaics with Dirina.
One of my favourite lichen names and handy as an expletive sometimes!!

Yes, I think you’re right. Most occurrences are turning out to be T. luekingii and it may be that T. lepadinum is rather actually quite scarce

Thank you. This is devastating news. I noticed the problem as I do Garden Birdwatch for the BTO. I had heard the disease had reached London.

What are its spot reactions? Is it C+?

Looks a lot like our Cladonia verticillata. Gorgeous!

Dramatic example of the pink fungus attacking the grey and yellow lichens! Probably a thing called Illosporiopsis christiansenii

Both these lichens occur on the north Devon coast, Dermatocarpon on rock on the beach and the Lecidella on cliff top sycamore. Have only found the Lecidella by the coast. Sussex is such an interesting place for lichens #lichensGBI#lichens

I guess it has cyanobacteria rather than green algae as its photobiont?

What a great black hypothallus! Accentuating the shape of the lobes

Not sure from your photograph but Parmotrema crinitum has cilia with the isidia on the lobes

Long purple flowers look like loosestrife Lythrum species?

L. gangaleoides is always on rocks. Cutting down through an apothecium shows dark pigment in T. atra and pale greenish in the Lecanora a good way to separate in the field

Looks like Tephromela. Not Lecanora gangaleoides I suppose?

The brown one looks like Anaptychia runcinata
