I love a summer drought, warm sunny days, a hose pipe ban to irritate those boring get a life middle aged men who spend Sunday mornings lovingly stroking and washing their cars but above all the big draw down zone at Llandegfedd Reservoir (LR). At this time of year that extensive muddy margin is ideal for passage waders, stone tuning and the occurrence of rice krispies. Yes, the liverwort and rice krispie lookalike Riccia cavernosa is now starting to show well on bare mud at LR. When mature this species forms an attractive rosette up to 3 cm in diameter. For more information on this and other mosses and liverworts I recommend getting your hands on the recently published Mosses and Liverworts of Britain and Ireland a Field Guide co-edited by local lad Sam Bosanquet. The guide gets a five star rating from me!
