Apiognomonia Höhn. 1917

This genus contains around 30 species of plant pathogenic fungi. These are found in the northern hemisphere, causing anthracnose diseases on forest trees. Several species are considered to be significant pathogens like Apiognomonia errabunda which infects oak trees in Europe and North America.

Like closely related genera, the species of Apiognomonia have small ascospores, usually less than 25 μm long. The perithecia arise separately from the surface, are upright with central necks, rarely eccentric. The genus can be distinguished from closely related genera by having unequally septate ascospores (Sogonov et al., 2008). The asexual forms have been described under the genus Discula.
