Today, looking for Sphagnum moss in the Alt Pirineu (high Pyrenees) natural park. At least two species found, plus many others mosses and liverworts. #bryophytes #mosses

A local ravine supports a wall of Plagiochila spinulosa, presumably a colony that is decades (if not longer) old, based on the thickness of the clumps. They of course fall off and I felt I had to place this huge piece back to another rock face! @bbsbryology.bsky.social

@bbsbryology.bsky.social folks - any tips on measuring production/phytomass in aquatic mosses? Stupid fish biologist begging for help.

Happy to announce our study that has just been published from work done during my PhD at the University of Bristol working in Prof. Jill Harrison's lab. It's about WOX genes and sporophyte development in the model moss, Physcomitrium patens. Take a look 🧵👇

Oedipodium griffithianum (Gouty-moss) looking rather good ,growing on acid soil amongst the Crags high up on Craig Cywarch on Sunday, a lovely species i have seen a few times ,love those Capsules with there thick Seta and the abundant Gemmae amongst the leaf axils,nice 🏴󠁧󠁢󠁷󠁬󠁳󠁿 @bbsbryology.bsky.social

An unusual find of fruiting Tetraphis Moss (Tetraphis pellucida) in Norfolk by the VC 27 recorder (Mary Ghullam). The distinctive four peristome teeth which can be seen in the images give the moss its name @bbsbryology.bsky.social @norfolknats.bsky.social

After several years in gestation, the long awaited paper on Aneura pinguis agg is now out. Lots of hard work from the team @thebotanics.bsky.social has resulted in the description of 12 species based on molecular and morphological criteria. Free to download at link.springer.com/article/10.1...

Adelanthus lindenbergianus(new site) recorded with @timoceallaigh.bsky.social, Ciaran & Shane in Connemara. This very rare liverwort is a member of hepatic mat community which includes Bazzania tricrenata, B. pearsonii, Herbertus hutchinsiae(2). Thanks for confirming @nimbosaecology.bsky.social

We helped save 5% of Scotland’s population of Aspen Bristle Moss. 🌿 This tiny, endangered moss grows only on Aspen trees and survives at just three sites. When one key tree fell, the moss it carried would have died without action. 🧵1/3

For the final day of the BBS Slovenia meeting we visited some lowland calcareous sites including the intermittent lake of Cerknica where we were distracted by a mass of Gladiolus illyricus before finding some splendid Drepanocladus lycopodioides. Later highlights included Drepanocladus trifarius.

Not many bryophytes in the Skocjan caves on day 5 of the BBS Slovenia meeting, but a fantastic experience. Outside were a good range of epiphytes including Orthotrichum patens and plants of damp limestone such as this fruiting Gymnostomum calcareum.

Over the Vrsic pass from Trenta on day 4 of the BBS Slovenia meeting. Some great montane species including Syntrichia norvegica with its reddish hair points.

Anastrophyllum hellerianum (Heller's Notchwort) a tiny liverwort of decaying rotting logs,I have only seen it on rotting Quercus petraea logs in Oceanic woodland in wales,here on a rotting pine in the Abernethy Forest a few weeks ago was nice,red Gemmae on the shoot tips @bbsbryology.bsky.social

Day 3 of BBS meeting in Slovenia. Heading up the Zadnjica valley. This is Microhypnum sauteri. A relatively recent addition to our own flora (from Inchnadamph in Scotland) but turning up here most days on sheltered limestone.

Day two of the BBS meeting in Slovenia. First a visit to the Juliana Botanic Gardens and then a walk down the Soca valley where we saw many interesting plants including Mannia triandra, seen here with Marchantia quadrata.

Southbya tophacea, one of the star liverworts of the British flora. My first time seeing Southbya in Britain and wow, they're such beauties! @bbsbryology.bsky.social

Cinclidotus aquaticus, not known from Britain/Ireland, growing submerged on limestone in the outflow stream from the Gjlun stream in the Soca valley, Slovenia.

First day of the BBS meeting in Slovenia, thanks to the kindness of Simona Strgulc Krajšek who has organised a fantastic programme for us. Today we explored the limestone thermophilous temperate woodland around Bovec in the Trenta valley and some aquatic habitats.
