Ammanford miscellany in SN61B

A population of Riccia subbifurca along a muddy track near Ammanford was unexpected. There were few other species of note other than Plagiomnium elatum, which was recorded nearby in marshy grassland in association with abundant Valeriana dioica. A pink Bryum, possibly pallens (still to check my specimen), was collected from an area of disturbed wet grassland, Physcomitrium pyriforme being the most frequent associate.

Orthotrichum pallens - a surprise from NE Wales

During my visit to Clwyd last week I collected an interesting-looking Orthotrichum from a Sycamore on the calcareous lead mine we were surveying.  Its orange-tipped, hairless calyptrae looked good for O. pallens, although I have recently been fooled by forms of O. stramineum so I wasn't too hopeful.  To my relief, a microscope check revealed nicely exposed cryptopore stomata, and removing a ripe capsule's lid released a peristome with 16 endostome teeth (8 in virtually all confusion species).  Hooray!


This is the second Welsh record following on from a few tufts on a Field Maple in a hedge at Dingestow, but given the rapid increase in this moss in England I'm sure it won't be the last Welsh record.
