Description:
Amauroderma s.lat. has been defined mainly by the morphological features of non-truncate and doublewalled basidiospores with a distinctly ornamented endospore wall. In this work, taxonomic and phylogenetic studies on species of Amauroderma s.lat. are carried out by morphological examination together with ultrastructural
observations, and molecular phylogenetic analyses of multiple loci including the internal transcribed spacer regions
(ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), the largest subunit of RNA polymerase II (RPB1)
and the second largest subunit of RNA polymerase II (RPB2), the translation elongation factor 1-α gene (TEF) and
the β-tubulin gene (TUB). The results demonstrate that species of Ganodermataceae formed ten clades. Species
previously placed in Amauroderma s.lat. are divided into four clades: Amauroderma s.str., Foraminispora, Furtadoa
and a new genus Sanguinoderma. The classification of Amauroderma s.lat. is thus revised, six new species are
described and illustrated, and eight new combinations are proposed. SEM micrographs of basidiospores of Foraminispora and Sanguinoderma are provided, and the importance of SEM in delimitation of taxa in this study is briefly
discussed. Keys to species of Amauroderma s.str., Foraminispora, Furtadoa, and Sanguinoderma are also provided.
