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!!

Blue black lichen crust on white painted gate in Carlisle

Neat little thalli on painted metal gate looking like Caloplaca chlorina. Found in the centre of Carlisle. Xanthoria parietina and Physcia tenella there too

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

Yes, I think you’re right. Rest our occurrences are turning out to be.T luekingii

I have noticed this too. Sorediate species like Physcia tenella, Parmelia sulcata and Hypotrachynas seem to thrive in apothecia like these perhaps because it’s like a tiny bowl in which water can be trapped. Just a guess #lichens #BLS

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.

PS blackbird post. Absence noticed in Devon. Could it be a local problem?

Where have the blackbirds gone?
My garden was never without a blackbird and this year there have been none visiting since the end of September. Has anyone else noticed their absence?

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

Many thanks to Becky Yahr and Erik Moller for a really helpful and inspirational workshop on Rhizocarpon held at the RBGE last week. So lucky to have expert Einar Timdal over from Norway too

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

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

White stipe? (Actually grey but illuminated by bright sun. Lecanactis abietina on Pedunculate Oak, Cow Wood SSSI. High Weald Ghyll Woodland yesterday.

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

Typical lichens of vegetated shingle in Sussex, at Tide Mills, Newhaven, East Sussex. Pebble with Rhyzocarpon reductum, Verrucaria nigrescens, and Xanthoria parietina, in a bed of Cladonia rangiformis and Sedum album. #lichenGBI @britishlichensociety.org.uk

These look like really good apothecia the fungus fruiting bodies

Lecanora expallens : England : VC25 East Suffolk : TM3389 : September 2022 : On sandstone gravestone

Field notes for Lecanora expallens! This one at Bungay, Suffolk, England. One of many 'dreaded' green sorediate crusts common in Britain, but which look very much alike. Fear not: this #lichen can be ID'd with care. See notes for help, plus bonus tabular key to GSCs! aspenecology.com/lecanora-exp...

Ophioparma ventosa

Pseudephebe pubescens

And finally from Bealach na Ba, lichens Ophioparma ventosa )not seen on Colonsay) and montane Pseudephebe pubescens. #LichenGBI

The view from Bealach na Ba

Lepra dactylina and Alectoria nigricans

Close up of Lepra dactylina

A not very good pic of the grey strands of Alectoria nigricans

We're now in Torridon for a week and stopped off at Bealach na Ba for a taster of montane lichens at just over 600m asl. We refound our find from 2021 of Lepra dactylina and Alectoria nigricans, not far from the car park at the top of the pass. #LichenGBI

Wow! Lotsa lungwort!

A lichen difficult to distinguish from Lecanactis abietina, L. subabietina and Opegrapha vermicellifera. Pd+ reaction would nail it. All 4 lichens scratch orange too #BLSlichens

Peased to see
Schizotrema (Schismatomma) quercicola on Quercus robur, in a Chalk & Clay-With-Flints SSSI ancient woodland, Downs, W. Sussex. A west country & south coast species. An NIEC 'old woodland' indicator. As all Schismatomma sp. scratches orange. #LichensGBI @britishlichensociety.org.uk
