Please look for Ulota
After several hints that Ulota taxonomy was about to change (is the information that Ulota crispa comprises three species a 'spoiler' or a cause for concern?!), British bryologists now have no excuse to bury their heads in the sand. Tom Blockeel has published an excellent overview of Ulota in the last Field Bryology, complete with a key and photos of endostome and exostome teeth. There are only a few Welsh Vice-counties listed for each segregate species, with Ulota intermedia in VC41 a bit of a surprise, so there's a lot to be found. With this in mind I have collected a few Ulota this summer, including U. crispa and U. crispula on willows at 300m altitude near Llyn Ogwen in Snowdonia (U. crispa photo above; I photographed the dull species); U. crispa on willows near Capel Curig; U. crispa on a lowland Hawthorn at Llangua in Monmouthshire; U. crispula on Hazel at 150m altitude at Gwernogle in Carmarthenshire; and U. intermedia on Lundy.
Now is the perfect time to look for U. crispula and U. intermedia, because both seem to have old/post-ripe capsules, whereas U. crispa is still unripe/ripe with calyptrae.
