River Clydach, Rhos

I spent about an hour this afternoon recording along this river, which from aerials looked to be the best habitat in SN70L. A small colony of Solenostoma paroicum with capsules was the only real highlight, otherwise there was nothing overly special, but I managed to boost the square total of 52 up to 91 taxa, the best of the rest including Heterocladium heteropterum var. heteropterum, Lejeunea patens, Marsupella emarginata var. emarginata, Nowellia curvifolia, Orthodontium lineare & Trichostomum tenuirostre.

Aberdulais Jungermannia query

Here are a couple of pics of the non-fruiting Jungermannia from the drippy cliff at Aberdualis – the assemblage included Tha.alo., Fis.osm., Pel.end., Cra.fil., Gym.aer., etc. so with some basic influence. I’m not expecting a definitive outcome but the purplish rhizoids and cell measurements [leaf cell width (n=10) 39.5µm & cortical cell width (n=10) 36.6µm] are suggestive of Solenostoma (J.) paroicum – any thoughts welcome.
