Abstract
Nomenclatural types of the basionyms of species of sequestrate relatives of Russula from Australia and New Zealand were studied and original descriptions emended. Illustrations of microscopic characters are provided for the first time for many species. Several recombinations are proposed, including: (i) Arcangeliella crichtonii comb. nov. (≡ Cystangium crichtonii), (ii) Arcangeliella hepaticus comb. nov. (≡ Elasmomyces hepaticus), (iii) Macowanites tomentosa comb. nov. (≡ Hydnangium tomentosum).
