Remarks (internal):Four species have been referred to Le Ratia, all described from New Caledonia and transferred to Leratiomyces by Bresinsky & Binder (1998). They were discussed by Heim (1968). Of these, L. smaragdinus (Pat.) Bresinsky & Manfr. Binder and L. atrovirens (R. Heim) Bresinsky & Manfr. Binder do not belong in this genus (see 'Excluded species'). Leratiomyces coccinea (Massee & Wakef.) Bresinsky & Manfr. Binder has not received further study. As currently understood the genus therefore contains 8 species and is widespread in both tropical and temperate regions. Although typically secotioid, most species now referred there actively discharge their spores. They are variable as noted in the emended diagnosis and it seems that the genus cannot be concisely defined morphologically.
