Identification notes

In the UK, most of the D. tophaceus we find is ssp tophaceus. However in spring 2021, Didymodon tophaceus ssp sicculus was found by Peter Martin growing on Lundy Island off the North Devon coast. It is new to Britain and amongst other characters is distinguished from ssp tophaceus by it’s nerve being narrower and having shorter cells over the ventral surface.
