Blue above, and blue below. Rather a lot of brambles though...

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!

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.

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...

No more delays: Let's get peat out of gardens once and for all. The time for uncertainty has ended.

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/...

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

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.
