The British Lichen Society
@BLSlichens
The British Lichen Society is for all interested in lichens worldwide. Lighthearted anecdotes and lively discussion are as welcome as in-depth detail.
A great weekend at the end of February for the BLS Winter Workshop at Preston Montford, led by Neil Sanderson, Brian Coppins & John Douglass, working through lots of problem specimens and a trip to Alcott Woodlands. Photos (c) Douglass #lichens

Kickstarting a weekend of #lichens with Silke Werth (LMU Munich) for the Swinscow Lecture, sharing research on genetic diversity & population structure of Lobaria & Sticta species on the Atlantic archipelago. Absolutely fascinating!!! #BLSAGM2025




A weekend of #lichens has begun at the Natural History Museum, for the BLS AGM 2025. What a wonderful turnout from our friends & colleagues across the globe. We have a great selection of talk this weekend - so stay tuned!! #BLSAGM2025


Lichens are becoming a frequent muse for artists. Which is not surprising considering how beautiful and amazing they are!
We are pleased to be hosting 'Becoming lichen' events - look out for the second event in January. The fruit of an exciting project between @NaturAmByth & movement artist Simon Whitehead, who's exploring how slow growing lichens may inform gentle movement, meditation & resilience
Due to unforeseen circumstances, we are now unable to print out photos for our photo competition to display at the BLS AGM. Instead, we aim to share an online folder with all entrants, AGM attendees, and BLS members to showcase the photos and to facilitate online voting.
