Finding out more about mosses and liverworts
Most people can recognise ‘moss’ when they see it, and a few can recognise a liverwort, but beyond this has usually been seen as the realm of the expert. Mosses and liverworts are small and have the reputation of being difficult to identify, but while a few species will always need a microscope to confirm identification, many can be identified at a glance and most can be identified with the aid of a hand lens. Unfortunately, the learning curve is steep at the beginning but, with a little persistence, the most common mosses and liverworts can be readily identified after just a few weeks. The British Bryological Society, a largely amateur society, has an excellent website which can offer assistance and encouragement and this society holds field meetings in Scotland on a regular basis. The website has lots of pictures and can provide links to many more. The Botanial Society of Scotland has a section devoted to lower plants and the Scottish Field Studies Council runs at least two courses on mosses and liverworts each year at its Kindrogan Field Centre, Perthshire.
