Anomalous Bristle-moss

I'm not really sure that I'll ever feel comfortable with the English names of mosses. They were contrived to make mosses more accessible to the general public, as many people are put-off by Latin names, but many of them just sound a bit bizarre to me. 

I collected this specimen last week and finally got around to identifying it this evening - a good occupation for a cold, wet night. Anomalous bristle-moss differs from most British members of the genus in growing on rocks or masonry rather than trees. It's more or less ubiquitous on concrete, gravestones, wall tops and other man made structures except in the most polluted parts of Britain. This one was growing abundantly on limestone gravestones in Stamford Cemetery.
