Two species, Cliostomum coppinsii Fryday & Kantvilas sp. nov. from Scotland, and Cliostomum praepallidum (Müll. Arg.) Kantvilas & Fryday comb. nov. from Tasmania and southern South America, are described, illustrated and discussed. Both occupy an unusual position within the genus on account of their atypically wide, ± polarilocular ascospores. Patellaria banksiae Müll. Arg., based on a collection from Australia, is lectotypified and reduced to synonymy with Cliostomum griffithii (Sm.) Coppins.
