Metamelanea umbonata new to the British Isles

Extract

During a visit to the Natural History Museum London I examined material of the genus Porocyphus from the British Isles. A collection labelled Porocyphus coccodes [Scotland, Forfar, Caenlochan, on damp, E-facing rock (±basic), 1700 ft, 10 viii 1968, P. James (BM)] turned out to be a well-developed specimen of Metamelanea umbonata Henssen. Another two specimens from Scotland sent to me for identification belong here as well: Mid-Perth, Bread-albana, Creag Mhòr, S-facing cliffs, 700–800 m, 27/39.35, 6 vii 1979, B. Coppins 4573 (E, hb M. Schultz); Angus, Caenlochan Glen (N side), Glasallt Burn, W-facing cliffs, on vertical flushed granite cliff face, 800 m, 37/17, 7 viii 1989, B. Coppins 13383 & O. Gilbert (E, hb M. Schultz).
