Abstract

A fungus causing false smut in the flowers of Murdannia keisak (Commelinaceae, Commelinales, Monocots) in Japan was morphologically identical to Ustilago aneilematis. The fungus infected ovaries of most flowers of host plants. Infected flowers were filled with yellow to orange thick- walled conidia that became olivaceous green at maturity. However, multilocus phylogenetic analysis of DNA sequences (18S, 28S, translation elongation factor 1α [TEF], the largest [RPB1] and the second largest [RPB2] subunit of RNA polymerase II) showed that the fungus belonged to the tribe Ustilaginoideae (Clavicipitaceae, Hypocreales, Ascomycota). Microscopic examination showed that the fungus developed conidia at the apex of conidiogenous cells, in contrast to other species in the Ustilaginoideae that develop conidia pleurogenously. A new genus, Commelinaceomyces, is formally proposed in the Ustilaginoideae to accommodate this fungus. Four species previously misplaced in Ustilago (Ustilaginales, Basidiomycota) are transferred to Commelinaceomyces, including the type of the genus, C. aneilematis, on Murdannia keisak. This is the first report of a clavicipitaceous species infecting host plants in the Commelinaceae.
