A coloured rating followed by an exclamation mark denotes that different ID difficulties apply to either males and females or to the larvae - see the species page for more detail.
Mosses
Mosses, liverworts and hornworts are small plants, commonly known as bryophytes. Though small, they are a fascinating and rewarding group for anyone wanting to learn more about them. As early colonisers they can be found in virtually all terrestrial habitats. Bare soil, wall tops, tarmac - indeed just about every crevice supports one or more species. As well as being all around us, they are a good option to study in January and February when most other plants and invertebrates are absent.
Facebook Group: Bryophytes of Britain and Ireland
The British Bryological Society provides some excellent online guidance to help identify mosses and liverworts.
The BBS guides to common mosses and liverworts are very useful.
Atherton, I., Bosanquet, S. & Lawley, M. (eds.) 2010. Mosses and Liverworts of Britain and Ireland: A Field Guide BBS is an accessible guide for non-specialists and is highly recommended. The BBS are currently planning a second edition.
Watson, E.V. (1981) British Mosses and Liverworts (3rd edition) CUP has keys that are more technical, based on cell shape and leaf characteristics that may require microscopic examination, but be aware that since it was published, there have been some changes in taxonomy, and some new species have arrived in the Biritish Isles.
To identify some mosses, you may need to look at the microscopic details of the leaves - e.g. the cell shape in different parts of the leaf; whether there is a nerve in the leaf; whether the leaf margin is toothed, etc. For most species, the leaves are just one cell thick, and the shape of cells can be seen at low magnification. The BBS website includes micro-photoographs of the leaves of some species, and the drawings in Watson (ref. above) are very helpful.
Moss specimens will keep for a long time in paper packets (not plastic) once they have dried out. They re-hydrate very quickly once water is added.
