Llangynidr Mountain

Steph took us up Llangynidr mountain to seek out ponds / lakes on Thursday and we recorded the vegetation we could along the way.

Llyn y Garn-fawr is not as large as depicted on the map - maybe because it now drains into a peaty sinkhole and not into the stream marked on the map. (The stream still exists as it gets fed by water from the area around it.)
But Steph had a rummage around for invertebrates

Common Cottongrass, Plu’r gweunydd or Eriophorum angustifolium was abundant as was its smaller relative, Hare's-tail Cotton-grass

We also visited the Chartist Cave which actually yielded many of the records we made - with several species of fern in the cave and a variety of other plants nearby in the collapsed limestone boulders.

Maidenhair Spleenwort, Duegredynen gwallt y forwyn or Asplenium trichomanes subsp. quadrivalens

Common Sedge, Hesgen gyffredin or Carex nigra

Last week I was in West Cork for the Bay run from Glengarriff to Bantry - as a spectator I might add. There was plenty to see botanically - they've had a slightly warmer spring than us. And on a favourite beach we saw a lot of this:

Oyster Thief, Colpomenia peregrina

I was able to find it on David Fenwick's excellent site Aphotomarine. See also his flora at Aphotoflora.

This is an interesting seaweed - Wikipedia has the following information:

"Colpomenia peregrina, sometimes referred to by its vernacular names Oyster Thief and Bladder Weed, is a brown seaweed not native to the British Isles, but recorded in Ireland since 1934. It appears to have been introduced from the Pacific and was first noticed in Europe in 1906 on oyster beds."

Before that I was at Porth yr Ogof and saw this:

False Puffball, Enteridium lycoperdon also called Reticularia lycoperdon

It's a slime mould fruiting body it seems - like a loose bag of goo to feel! On a Hazel trunk. Thanks to Lorraine who found out what it was.
