Camilla atrimana

Plumose arista with long rays above and very short rays below, crossed P bristles and a spine on the ventral side of the fore femur should get you to Camillidae. Only about 5 species on the British list. This one shows a pointed apical section of the wing which suggests C.atrimana. C.acutipennis looks to be lumped with C.atrimana. Caught in Somerset at Crook Peak on 6/9/18

Didymodon tophaceus

This is one I found this morning on the coast. Under the microscope the leaves look distinctive having the shape similar to a Zygodon with the costa being in a channel. I eventually identified it as either Didymodon luridus or Didymodon tophaceus. It was a bit of a tough call but eventually I went with Didymodon tophaceus because of the leaf shape and the habit of the leaves when dry as D.luridus has appressed leaves when dry and D.tophaceus has it leaves incurled and slightly twisted.
