Apiognomonia hystrix (Tode) Sogonov, 2008
on woody plants
usually an asymptomatic endophytic leaf fungus. It strongly develops within the galls of Acericecis vitrina, choking the larva, and causing the galled tissue to fall out of the leaf. More fungal species behave likewise, but this is the most numerous one.
The teleomorph forms black perithecia with a long neck on fallen leaves and dead branches. Ascospores 1-septate.
Mainly known from maple, but also occurring on other tree species.
