Calosphaeriales

This order contains fungi with small, simple and dark perithecia as well as unitunicate asci that produce hyaline or slightly pigmented, ellipsoid or elongated ascospores. The species appear to be similar to the Diaporthales. They are saprobes and also include several important plant pathogens like the species of the genus Phaeoacremonium with the grapevine pathogen Phaeoacremonium aleophilum. These cause wilting, stunting and dieback diseases on grapevine and other crops.

The taxonomy of the order is under revision and studies conducted so far on the DNA structure of its members appears to indicate that it is polyphyletic.


The following genera are currently entered in the system:
