Wonderful to welcome @bbsbryology.bsky.social to the Natural History Museum this weekend for the autumn meeting. Fog hanging low over the Thames this morning as some of the group join our urban excursion (first mossing trip of the new season for me!)

Neil Bell from @thebotanics.bsky.social talking about merging spatial distribution of bryophytes with phylogenetic proximity to give an index of phylogenetic diversity. At our AGM at the Natural History Museum, where we also had a tour of the bryophyte herbarium. Thanks @jowilbraham.bsky.social !

Had a quick check in our seaweed press from Isles of Scilly trip a couple of weeks ago - looking 👌

Stumbled across an absolute riot of Riccia growing between daffodil rows and tractor tracks beside this field on Isles of Scilly. We think the extensive rosettes, with slightly perforated thallus, are Riccia crystallina...

Another street tree epiphyte that's becoming more common in London - Orthotrichum tenellum forms small neat cushions with notably long capsules and calyptra. The leaf tips also have a distinctive beak at the end. Another bryophyte taking advantage of the cleaner air!

The 'algal gloop' here growing on a nice garden wall of mixed mosses. Will be interesting to keep an eye on this. Microscopy revealed one dominate green alga, rapidly reproducing. These particular algae v difficult to identity!

I was admiring the luxuriance of South London bryophyte epiphytes yesterday. Street trees carpeted in Syntrichia papillosa; huge cushions of Pulvigera lyelii... some nice species diversity but also saw 'algal gloop' smothering wall top mosses. Nitrogen pollution impacting in different ways.

Oh fantastic! Haley mentioned you were visiting in Jan but hadn't clocked date.

I love these posters Astrid! Created by Barbara Nicholson in the 1970s, commissioned by Natural History Museum. I found the seaweed one and have that up in the algae herbarium.

Thanks Tim, glad you like the book. Fantastic to see 'Mosses' out in the wild!

Sign the petition asking the Government to finally end peat compost sales with legislation in 2026 - no more delays. It’s been a long and tiring road to get peat compost banned and we need your signatures and shares now more than ever to get it done. actnow.peatfreepartnership.org.uk/end-peat-sal...

What a delight to visit fragments of temperate rainforest on Dartmoor. These fragile and fragmented habitats were once much more extensive. Dripping with both rain and bryophytes.

I was so happy to attend the International Association of Bryologists conference in Taiwan last week - Organised by the Taiwan Biodiversity Research Institute and the Taiwan Bryological Society. Interesting presentations, good chat, and some time to get into the mountains to mingle with moss 💚

Journeying home from a fantastic @bbsbryology.bsky.social meeting this weekend - interesting to visit Thorne Moors, an area ravaged by industrial peat extraction which ceased in early 2000s. Conservation management in the region now focused on rewilding and restoring precious peatlands.

This is infuriating. What is the point of a Marine Protected Area if trawlers are allowed to keep ploughing it? Yet again, the government has succumbed to commercial lobbying. www.theguardian.com/environment/...

Thanks George for your kind comments. I worked really hard on the book, though doing the research was a joy! I found it really interesting to navigate at that higher taxonomic level and it meant I ended up looking into obscure genera that turned up interesting perspectives!

Jo Wilbraham @jowilbraham.bsky.social · 08/08/2025

Hi Kathleen - wow thank you so much. I've never been on ticktock but that sounds great. I hope the book helps spread some love and awareness for our favourite plants!

And so ends a magnificent week mossing around Frieberg and the Black Forest! Huge thanks to Michael @milueth.bsky.social for leading our excursion and sharing some very special places and plants with us. - BBS excursion to SW Germany @bbsbryology.bsky.social

Today we lunched amongst castle ruins home to four Schistidium species. A good chance to compare, contrast and be confused by this tricky genus. - BBS excursion to SW Germany @bbsbryology.bsky.social

Jo Wilbraham @jowilbraham.bsky.social · 10/04/2025

Today, we bryologised atop Feldberg, Germany's highest (after the Alps..) mountain at 1400m. Many wonderful species, with Ptychostomum (Bryum) schleicheri and Bryum weigelii looking particularly sensational. - BBS spring meeting in the Black Forest @bbsbryology.bsky.social

Jo Wilbraham @jowilbraham.bsky.social · 10/04/2025

Fantastic to see SO MANY Grimmia species on our trip around SW Germany. These cushions are Grimmia montana. Apparently the female plants of this species (quite rare) typically form more rounded cushions than the flatter males... @bbsbryology.bsky.social

Visited a Sphagnum bog this week - there to look at the bryophytes but also fun to check in on the desmid algae situation! These tiny green jewels were hiding in submerged Sphagnum cuspidatum

I was introduced to a tiny moss (new to me) at the weekend on our BBS London group walk over chalk grassland. Seligeria calycina grows directly on the chalk, visible from afar only as small dark brown patches around the edge of pebbles.
