Wernddu revisited

Well this time the Red-flanked Bluetail gave itself up readily and on our circuit back to the car I stopped briefly at what looked like the remains of an old lime kiln. Amongst some fruiting Leiocolea turbinata was the tiny Fissidens crispus (=limbatus). NB smallest tick marks below = 1μm and note protruberant cells.

  1. Ooh I find Leiocolea troublesome - those leaves look pretty wide-based/decurrent and I wonder whether it might be L badensis. Did you check the perianths for trigones? Similar plants we saw at Castell Coch lacked leaf cell trigones but did have trigones in the perianth cells :-(

    I'm glad you saw the Bluetail.

  2. I can see what you mean with the shoots in the image, but the ones I looked at in the field were typically very narrowly inserted - I'll check the specimen. Do they ever grow together?

  3. Just checked and there's a little thickening on the cell 'corners' on the perianths (see added photos) but not sure they constitute trigones, also leaves mostly look narrowly inserted to me, except those below the perianths, which match turbinata in Paton.

  4. Nice one Barry. Can you post a grid ref, so I can have a look at the F. crispus if I'm in the area? Thanks.

  5. It's just off the muddy path used by mountain bikers at ST17218532

  6. The whole area looks very mossy so well worth exploring further - good luck
