The nomenclatural status of the 21 specific names in the British checklist affected by the abolition of later starting point dates for all fungi is discussed. Two are completely unchanged and the author citations of 15 are simplified by the deletion of previously ‘revalidating’ authors. Six alterations in name prove to be necessary: Microcalicium disseminatum (Ach.) Vainio for M. subpedicellatum (Schaerer) Tibell, Mycocalicium subtile (Pers.) Szat. for M. parietinum (Ach. ex Schaerer) D. Hawksw., Mycomicrothelia melanospora (Hepp) comb. nov. for M. atomaria (DC. ex Merat) Keissler, Opegrapha parasilica (Massal.) Vězda for O. persoonii (Ach. ex Gray) Chev., Orphniospora moriopsis (Massal.) comb. nov. for O. atrata (Sm.) Poelt, and Stenocybe pullatula (Ach.) B. Stein for S. byssacea (Fr.) Körber.
