The magic few weeks of spring when Blackthorn, Prunus spinosa, flowers before it produces leaves, and on the Sussex coast (here RSPB Pagham Harbour) the buds and the blooms form a continuous abstract impressionist canvas with lichens, mostly Ramalina species. #lichenGBI #blackthorn #spring

I wrote something about he recent lichen trip to Barbondale

I'm out west this week surveying some patches of woodland on the Balmacara estate outwith the well known Coille Mhor SSSI. There's some amazing lichens about, like these lovely Pseudocyphellaria citrina and P. norvegica. #lichenGBI

Lichen klaxon alert!!! An eagle-eyed friend found something she thought "looked rather like something I'd seen in the book". Teloschistes chrysophthalmos (AKA Goldeneyes) has made it to Cumbria. Just a bit further north than previously found... so keep checking those hawthorns everyone! #LichenGBI
A pleasant- if chilly- afternoon wander in the woods revealed primroses, some unexpected Arthonia vinosa on an old oak, a nice patch of Sphaerophorus globosus on a crag and fertile Scytinium lichenoides 'neath a mucky quarry spoil tip ash. #LichenGBI
On the bak of an old Birch tree.
On mossy rock - mostly on the moss.
Two photos of #lichen I took last May in Glen Affric, Scotland. I'm a lichen beginner, any help towards an ID would be appreciated. The first is on an old Birch tree, the second on a mossy rock, most on the moss rather than the rock. The apothecia of both are about 1cm diameter. #lichenGBI

Bit of a dog lichen day yesterday pottering up the beck in Barbondale with Cumbria Lichen and Bryophyte Group. Here's Peltigera leucophlebia and P. praetextata. #LichenGBI

Had a good day at Glasdrum NNR filling a few gaps in my knowledge of Scottish rainforest lichens with the help of Oliver Moore. This was the find of the day, the nationally rare jelly Leptogium hibernicum.

Very pretty Flavoparmelia sorediens on worked wood (fence rail) at Brede, East Sussex. Nearly all the F. sorediens I have seen has been on fence rails. #lichenGBI
Tiny rosette of brown cylindrical branches, less than 1cm across, on limestone
Underside of small limestone block showing several thalli of Scytinium massiliense, as well as some dark Verrucaria nigrescens
Minute jelly #lichen less than 1cm across whose preferred habitat is underside of small limestone blocks in scree. Scytinium massiliense, from upland Cumbria, with tiny cylindrical nodulose branches. Distribution sparse in UK but is it overlooked? #lichengbi

Thelopsis corticola, orangey soredia with all-negative chemical tests, unlike some lookalikes which have pink/red reaction in C.
Lopadium disciforme can be spotted on old broadleafed trees by the grey-green smurr of miniscule squamules. This one fertile - tiny black chunky apothecium visible.
Tiny #lichen in old woodland remnants, Cumbria, seen when looking closely with good handlens at an old oak. Thelopsis corticola has thin grey-green thallus, buff-orange soredia, not common in the north. Lopadium disciforme has minute green squamules w pale edge, uncommon in most England #lichengbi
A tiny example of the Goldeneyes lichen or Teloschistes chrysophthalmus, about 5mm across with only one fruit or apothecia. The fruit is circular, golden orange and surrounded by cilia that look like eyelashes, which is where it gets its common name. The lichen was found on Hawthorn on Devils Dyke, part of the South Downs, in Sussex.
An example of the Goldeneyes lichen or Teloschistes chrysophthalmus, about 1cm across with no fruit (apothecia.) The lichen was found on Hawthorn on Devils Dyke, part of the South Downs, in Sussex.
A larger example of the Goldeneyes lichen or Teloschistes chrysophthalmus, about 2cm across with lots of fruit or apothecia. The fruit is circular, golden orange and surrounded by cilia that look like eyelashes, which is where it gets its common name. The lichen was found on Hawthorn on Devils Dyke, part of the South Downs, in Sussex.
A good day to check on the Goldeneyes lichen - Teloschistes chrysophthalmos - on Devils Dyke on the South Downs above Brighton - lots found - from a tiny one with a single 'eye', ones with no 'eyes' to lots of 'eyes'. #lichen #lichenGBI @friendssouthdowns.bsky.social @nationaltrust.org.uk
Zwackhia prosodea, on the shaded side of an ancient Quercus robur. A lichen entirely of the far south. It's mostly on Oak and Yew. I have only seen it in three other places in Sussex; all on churchyard ancient yews. In a Low Weald ancient woodland shaw @britishlichensociety.org.uk #lichenGBI NS & NT
Looking at this again I am wondering whether this Pertusaria hymenea's apothecia have been infected with the lichenicolous fungusc Lichenodiplis pertusariicola? Any thoughts any one? #lichenGBI
2/2. Nearly every part of this Ash's trunk & branches are covered in lichens & bryophytes. It's harder to notice this continuous biodiversity along ash's trunks when they are alive and standing. Ash is probably second only to Oak in terms of lichen diversity. @britishlichensociety.org.uk #lichenGBI
2/2 in Sussex; but it was too high up to get a sample. The Lullington Heath Hawthorns are covered in lichens, like coastal Hawthorns; but there are slight differences in their communities. Chalk heath hawthorn have Usnea cornuta & Hypogymnia physodes which are absent on costal Hawthorns #lichenGBI
1/2 Trees with abundant Usnea spp. are not common in Sussex. But this Hawthorn in Lullington Heath NNR, chalk heath (loess: wind blown acid soil on chalk) has abundant Usnea right at its top. It looks like U. articulata, String of Sausages; which is rare @britishlichensociety.org.uk #lichenGBI

Found a lichen lifer today, Catolechia wahlenbergii, one of our rarest arctic-alpines. In Glen Nevis, VC97. Last official record from the area in an adjacent monad was 2003. What a beauty! #lichenGBI
