Diaporthales


Diaporthales is an order of sac fungi.
Diaporthales includes a number of plant pathogenic fungi, the most notorious of which is Cryphonectria parasitica Barr, the chestnut blight fungus that altered the landscape of eastern North America. Other diseases caused by members of this order include stem canker of soybeans, stem-end rot of citrus fruits, and peach canker disease.
Some species produce secondary metabolites that result in toxicoses of animals such as lupinosis of sheep. A number of asexually reproducing plant pathogenic fungi also belong in the Diaporthales, such Greeneria uvicola Punith., cause of bitter rot of grape, and Discula destructiva Redlin, cause of dogwood anthracnose, both of which are mitotic diaporthalean species with no known sexual state.

Genera ''incertae sedis''

The following genera within the Diaporthales have an uncertain taxonomic placement, according to the 2007 Outline of Ascomycota. A question mark preceding the genus name means that the placement of that genus within this order is uncertain.
