What is "diaporthe"

Diaporthe is a genus of endophytic filamentous fungus plant pathogens.

Diaporthe species have been shown to transform the infection-inhibiting factors - catechin and -epicatechin into the 3,4-cis-dihydroxyflavan derivatives

Some species, like Diaporthe toxica, produce secondary metabolites that result in toxicoses of animals such as lupinosis of sheep.
