Abstract

Verrucaria elaeomeleana (Massal.) Arnold s.str. is confirmed for the British Isles and its separation from V. funckii (Sprengel) Zahlbr. is discussed. Additional records are provided for V. latebrosa Körber. Verrucaria aquilella Nyl. and V. fuscocinerascens Nyl. are confirmed as synonyms of V. aethiobola Wahlenb., while V. conturmatula Nyl. is shown to be based on immature material of Polycoccum microsticticum (Leighton ex Mudd) Arnold growing on Hymenelia lacustris. The British record of V. amylacea Hepp is referred to V. praetermissa (Trevisan) Anzi, and that of V. collematodes Garov. is referred to V. fusconigrescens Nyl.
