It has been derived from a number of published lists including Saccardo’s Sylloge Fungorum (contributed by SBML, USDA), Petrak’s Lists, Saccardo’s Omissions, Lamb’s Index, Zahlbruckner’s Catalogue of Lichens (comprehensive for names at species level only but with an increasing number of names of infraspecific taxa) and CABI’s Index of Fungi.
