ABSTRACT
Stigmatodiscus touroultii (Stigmatodiscaceae, Stigmatodiscales) is described and
illustrated from corticated dead twigs of Salvadora angustifolia collected in Juan de Nova
(Scattered Islands, Mozambique Channel). It is characterized by the irregularly shaped pruinose
hymenial disc without distinct black marginal lips and a calcium oxalate crystal layer
in the epithecium. Phylogenetic analyses of a multigene matrix containing a representative
selection of Dothideomycetes from four genes (nucSSU-ITS-LSU rDNA, RPB2, TEF1 and
TUB2) revealed a highly supported placement within Stigmatodiscus as sister species to
Stigmatodiscus oculatus. Micromorphology of the sexual and asexual morph matches the
genus Stigmatodiscus. A key to all known species worldwide is provided.
