This revision of cuboid-spored Entoloma in Madagascar is based on the exami
nation of type material described earlier by Romagnesi and new collections
made by the first two authors. Entoloma pseudoheimii sp. nov. and E. rufovi
nascens sp, nov. are described, and two new combinations made: E. cuboidosp
orum var. chromostomum, and E. heimii combs nov. A key to the madagascarian
cuboid-spored species of Entoloma is provided.
