Perithecia are pore-like or flask-shaped structures through which spores are released. The texture of this surface is leathery and smooth. The edge of the fungus is orange to cinnamon brown. Diatrype stigma is a saprobic fungus usually found on hardwoods. It has a preference for beech trees. It belongs to the Xylariales order and the Diatrypaceae family.
