Lichens

Teloschistes chrysopthalmus

Lichens come in a vast array of shapes and colours. Though daunting at first, there are many common species which can be easily identified once you know what to look for. Cornwall is also home to many rare and in some cases bizarre species. Bob Hodgson from the British Lichen Society will guide you through the fundamentals of the structure and ecology of lichens and get you started on learning how to identify them.
