Abstract

The identity and diversity of Kordyana species on three native species of Commelinaceae in Australia were studied following surveys in 2020–2022 for Kordyana brasiliensis, which had been deliberately released as a biocontrol agent for the environmental weed Tradescantia fluminensis. Three new species of Kordyana are described from Australia based on DNA sequence analysis of the ITS and LSU rDNA regions, morphology, host associations, and geographic distributions. Two new species, Kordyana spectabilis on Aneilema acuminatum and Kordyana luteoalba on Pollia crispata, occur in shaded rainforest habitats in eastern Australia. The third new species, Kordyana occidentalis on Commelina ensifolia, occurs in forests and woodlands of the Kimberley region of Western Australia. Morphological descriptions are provided for these three new species of Kordyana as well as for the conidial stage of K. brasiliensis.
