Every autumn and winter, the thallus of this liverwort, Endive Pellia (Pellia endiviifolia), grows branches at the tips. Why? No idea. But I think it’s FAB 😍

Found myself some Leucodon sciuroides finally.

Botanical University Challenge #BUC2023. More #botanical words, this time for shapes #leaves, the light harvesters and food synthesisers of #plants.

Pleasure meeting with Rory Hodd of @NimbosaEcology yesterday, in Derrycunnihy Wood in Killarney. Loads of wonderful oceanic finds, just a selection here: 1. Bazzania tricrenata 2. Adelanthus decipiens 3. Sematophyllum demissum 4. Lepidozia cupressina

Bryophytes are abundant in the very wet conditions on Kinabalu, Sabah; this rather nice 'tree moss' with thick woody 'stems' is locally abundant on fallen logs. Any ideas on this one @BryophyteSurvey BBSBryology ?

A few colonies of Orobus Seed Liverwort (Targionia hypophylla) at Cwm Ivy today, new for Glamorgan; seen here growing with Hemisphaeric Liverwort and the Nationally Rare Pretty Cord-moss. Plenty Rose-moss too BBSBryology

Yesterday I went to look for Anastrophyllum saxicola which is a very rare liverwort in Scotland. My hunch paid off when I found it, in this boulder scree I've had my eye on for a while, AND Wilson's filmy fern (Hymenophyllum wilsonii) which is pretty scarce in the Cairngorms NP.

A great Irish Bryophyte Group meeting to Deputy's Pass, Co. Wicklow today - delighted to have Professor Daniel Kelly join us. Find of the day was Porella arboris-vitae by @BlackthornEcol - first record in the east of Ireland since 1975. And we even found some stubble.

Neckera (Leptodon) smithii, here rolled up tightly on an 18th century gravestone, Wootton.

A beautiful mixed cushion of Bryum pseudotriquetrum and B. alpinum, found in an upland flush near Lough Acoose. Shown are the most distinctive features of both - B. pseudotriquetrum with decurrent leaves and B. alpinum with long, red-nerved ones.

Mylia anomala, a gemma-producing relative of the stunning Mylia taylorii, on a boggy hillside near Glanteenassig, Kerry today

A very attractive display of the common Potamogeton polygonifolius (Bog Pondweed) on a track near Glanteenassig on Tuesday. This large genus requires some careful inspection to identify - in this case the lack of a hinge-like joint between stipule and leaf is key.

Gymnomitrion crenulatum on the ascent to Más an Tiompán. An extremely small liverwort that tolerates exposed slopes. The common name is "frostwort", and this impression is created by the transparent leaf margins.

The BBS depends on the goodwill of volunteers to keep on running, and unfortunately is having problems finding someone to act as Treasurer. Is there a financially literate bryosympathetic friend out there who might be able to help? Please RT (or is it RX?) britishbryologicalsociety.org.uk/call-for-actio…

If anyone is interested, Des Callaghan has put some freely available, absolutely stunning bryophyte photos from western Canada onto his website. Really worth a look. He even saw the enigmatic moss Takakia lepidozioides. bryophytes.myportfolio.com/canada-british…

Oligotrichum hercynium, a tiny moss that grows in a similar habitat to its relatives Pogonatum urnigerum and P. aloides, namely acidic, sandy soil, often found on tracksides.
