Sclerophora is included in the family Coniocybaceae (Eriksson et al. 2004; Pennycook & Galloway 2004; Eriksson 2005), though Tibell (1997: 311; 1998b: 108) keeps the genus in family Sclerophoraceae. It comprises six widespread species (Tibell 1999c; Kirk et al. 2001), of which two are recorded from New Zealand – formerly in the genus Coniocybe (Tibell 1987). The taxon Coniocybe otagoense Js.Murray (Murray 1960a: 182) is a non-lichenised fungus (Tibell 1987: 273).
