Diaporthe toxica (Williamson) is a plant endophyte and occasionally a plant pathogen ^[1]. D. toxica produces secondary metabolites that result in toxicoses of animals such as lupinosis of sheep. Mycotoxic lupinosis is a disease caused by lupin material that is infected with the fungus ^[2]. The fungus produces mycotoxins called phomopsins, which cause liver damage. Lupinosis has been incorrectly attributed to Diaporthe woodii but has now been shown to be a mycotoxicosis caused by the recently discovered teleomorphic fungus Diaporthe toxica ^[3]. The discovery and naming of this new fungus concludes over a century of investigation into the cause of lupinosis since the first outbreak in Germany in 1872.
