Ooh - that does look like a match - thanks...
E herbarium specimen - matchbox containing Epilichen scabrosus now Catolechia scabrosa
Last year when there we saw a matchbox containing Epilichen scabrosus now Catolechia scabrosa. Both corks and matchboxes were probably to hand for some eminent lichenologists - but a matchbox is probably a better container...
😍 Great to see some lichen love from April Windle of the @britishlichensociety.org.uk, plus our own Bill Bealey explaining how our LicheN app is used for measuring sensitivity to nitrogen pollution

Lichenomphalia ericetorum amidst other lichens and moss (by Caz)
Lichenomphalia umbellifera (now L ericetorum) as seen in the Cumbria, UK...
Graphis inustuloides with lirellae emerging from thallus with thalline margin surrounded by cracking
Graphis inustuloides multi-septate spores
Good find.
Strangely enough, I just looked at a specimen from Knapdale, west coast of Scotland, and it was Graphis inustuloides, Graphina anguina as was. #LichenGBI

Cetrelia olivetorum var cetrarioides on an oak tree.
Hypotrachyna laevigata
3 folk on a steep hillside looking for lichens
Bunodophoron melanocarpum- the trumpets are fruiting bodies with a black spore mass. This is the only known population in the Windermere or Coniston catchments.
Enjoyable Saturday in the woods near Tilberthwaite with Cumbria Lichen and Bryophyte Group. Lots of good acid bark stuff including (everybody's) favourites Cetrelia olivetorum; Hypotrachyna laevigata and Bunodophoron melanocarpum. #LichenGBI

You'd best ask Richard Brinklow - see BLS officers page. So far we've rarely gone back to look at old confirmed specimens but occasionally will try to identify unknowns.
I saw the same photos probably and they don't look the same, nor does the one LF mentioned. Desperate stuff!
Hear from Scot ex-diplomat Craig Murray independent journalist in Venezuela - seems very normal, with no shortages, no repression and good 4G! "Pretty well everything that I have read by Western journalists...turns out to be an absolute lie"

Parmotrema crinitum - with fruit?
Does Parmotrema crinitum have fruit like this? Or is it an LF? #LichenGBI
Menegazzia terebrata: close-up of holes (without soredia) with soralia visible on some lobe ends
Menegazzia terebrata rosette on rock

Pseudocyphellaria citrina on rocks nearby
One of our star lichen finds today in Knapdale was Pseudocyphellaria citrina (Yellow specklebelly) with lots on one willow and some on some nearby rocks. The yellow colour somewhat dulled perhaps due to being wet. #LichenGBI
A hazel covered in Ricasolia virens
Lovely woods with Lobarina scrobiculata just visible in the centre
View over the woods at Ardminish to Loch Stornoway
Very invasive and destructive Rhododendron in the wood at Ardminish.
Today we visited the woods at Ardminish south of Loch Stornoway in Knapdale - some lovely 'temperate rainforest' but spoiled by rhododendron that's already spreading badly. In 10/20 years much lichen, bryophyte, fungi and flora will be lost. Spread from nearby gardens and big houses. #LichenGBI
