Doctoral candidate studying temperate rainforest bryophytes at Edge Hill University
A tree clothed in the Filmy-fern Hymenophyllum tunbrigense at Ceunant Llennyrch NNR. Transported for a moment to the Macaronesian laurissilva. We can only imagine what virgin temperate rainforest looked like in the Welsh uplands now - perhaps this was a more common sight @bsbibotany.bsky.social

The leaves of the moss Dicranodontium denudatum break off easily and act as vegetative propagules. They are very "sticky" too, at least when wet. Was perhaps an even more efficient method of dispersal when more large animals like deer, boar, and moose roamed our woodlands. @bbsbryology.bsky.social

Trees covered in the hyperoceanic liverworts Plagiochila spinulosa (left) and Scapania gracilis (right) in the temperate rainforest at Coed Hafod-y-Llyn, Gwynedd. @bbsbryology.bsky.social

Willow Feather-moss (Hygroamblystegium varium) on stones in willow carr around the edges of a dried-up reservoir. It probably spends much of the year at least partially submerged, as the surrounding soil was sprouting 100s of plants of Physcomitrium pyriforme and P. patens. @bbsbryology.bsky.social

Sausage-shaped antheridia (reproductive structures) from male plants of the moss Zygodon conoideus. They are surrounded by paraphyses (unicellular strands) and produced in a rosehip-shaped perigonium. Many bryophytes produce reproductive structures at this time of year. @bbsbryology.bsky.social

It was nice to find a mega colony of the uncommon hyperoceanic liverwort Metzgeria leptoneura in North Wales recently. Very surprised that it doesn't seem to have been noticed at this otherwise well-recorded site before.
