(Dicks.) Grolle
A very slender, Suboceanic, dioicous leafy liverwort with stems no greater than 0.5mm wide and tiny leaves about 0.25mm long which are divided to the base into 3 or 4 finger-like lobes. It grows in small patches among Sphagnum in very wet areas of bogs and also in fens, on wet heaths and in flushes and it usually has to be searched for. It has a western and northern distribution in Britain and it is found in suitable wetland sites throughout Wales. In West Glamorgan it occurs in the Sphagnum bogs of the Gower Commons, Fforest Goch near Rhos and in the wetlands of Crymlyn Fen and Gors Llwyn. Sporophytes are occasional, but often difficult to find.
