Quick Summary

Botryosphaeriales is an order of fungi within the class Sordariomycetes. These fungi are characterized by their flask-shaped fruiting bodies, called perithecia, which contain sac-like structures (asci) that discharge spores through an opening called an ostiole.1

Many species within Botryosphaeriales are known to cause diseases in plants, leading to issues like cankers, blights, and leaf spots. Examples of genera within this order that are significant plant pathogens include Diaporthe and Gnomonia.12
