The cost of natural history books can be a barrier for naturalists, which is why NNNS teamed up with the Ted Ellis Trust to put together a research library (which is held at Wheatfen). If there are any field guides or ID books you think we should have then let us know
A new colonist has appeared on the pantiles of the outhouse roof. The darker thalli belong to Buellia aethalea (Catillaria atomarioides is also present on the tiles). What are the little colonists with paler thallus? Thread
It looks as if this monument was buried for so long thart it's lichens all died. Ivy and bramble may be good for some wildlife but lichens can't survive in their shade.

This iconic flora sold throughout Northern Europe. Sadly we decided not to reprint again once work on the third edition started. All but two large families and a few small genera have now been rewritten. See britishlichensociety.org.uk/identification…

These fantastic woodland sites are unique even amongst temperate rainforests. In the SW the higher temperatures reached in summer, results in a slightly different suite of lichen species compared to the more northern UK rainforests.

Pinheads are tricky to photograph. This great photo clearly shows both why they're called pinheads and the underlying crustose thallus.

Some surfaces are definitely easier for lichens to set up home on. It doesnt seem to be the paint that's important here but the textured surfaces.

How many lichens can you fit in one small space? Gorgeous.

Lovely resources for children. More on lichens in churchyards can be found on the Caring for God's Acre website. Including 3 videos with April Windle. caringforgodsacre.org.uk/resources/film…

People often remember that Normandina pulchella grows with mosses. But, in fact, it likes liverworts too. It's a species that benefits from the extra water that bryophytes trap and hold near the bark surface.

Always great to have uptodate information for lichen distribution. Thank you.

Many of us feel furious about the state of the UK's rivers––but also powerless. Now @kcllegalclinic have launched a 130-pp toolkit for change. Citizen science, FOIs, reporting, legal remedies: it's all here. It's brilliant. Read it, share it, fight back! kcl.ac.uk/legal-clinic/a…

Lecidella elaeochroma was frequently seen on climbing garden rose stems at RHS Garden Rosemoor in Devon last year during the planning of a lichen trail.

Rinodina sophodes from same High Force oak twig as in my Lecanora hybocarpa auct br and Unguiculariopsis thallophila posts below (VC66/NY82/Dec23). Despite appearances, Rinodina belongs to Physciaceae family of otherwise mostly foliose #lichens. Thread. /1 x.com/specanatura/st…

Did you know that lichens need rain & humidity to thrive? They can't hold water like plants, so when it's dry they go dormant. When it rains, they absorb water from the atmosphere & start to photosynthesise. That's why #ScotlandsRainforest is perfect for lichens. 📷 Niall Benvie
Indeed! Should've thought to measure thalli: say 2cm radius. Assuming 2-3mm/yr growth rate, that's ~10 stable years. Likely more. On crest of beach, ~2-3m above tide, among substantial heather, probably not frequently approached by feet. Seems plausible! link.springer.com/article/10.100…

Midwinter is stick season in the woods making the weird and wonderful more visible! A great time to look for lichen and 🍄 Pics from Hermand Birchwood. Go outdoors today 🙂#12dayswild #lichen #fungi #pixiecuplichen #wetwoodland #macrohour #TwitterNatureCommunity #westlothian
Very surprised & pleased on a walk to Nettlebed common claypits woodland in S Oxon to find this branch fallen from an ash tree with the unmistakable #lichen Usnea articulata with its long trailing branches & 'strings of sausages'. Only ever seen it in Devon before. Cleaner air?
Is Usnea articulata spreading back into areas where it has long been extinct? Pale green dots are 1650-1959. This photo is from Cornwall but I will quote-tweet an exciting recent discovery from S. Oxon in the next tweet in this thread.
@BLSlichens @BritMycolSoc So I conclude T. delicata. Its extreme rarity reflects underrecording, but it's still thrilling to add to the small handful of UK finds. Grateful for @FayrnHawk's agreement on ID via the fungi forum. @rob_yaxley: an LF first for Norfolk that I'll record via usual channels. /7x
