Abstract

Two new species of Sistotremastrum collected in French West Indies and French Guyana are described and illustrated. Morphological studies and molecular sequence data from two ribosomal DNA regions (ITS and 28S rDNA) support the recognition of S. fibrillosum and S. aculeocrepitans, two species characterized by their hyphal cords and basidia with 4 sterigmata.
