Apiognomonia hystrix

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.


Sapindaceae, etc.

Acer pseudoplatanus.

Mainly known from maple, but also occurring on other tree species.


Cryptodiaporthe hystrix (Tode) Petrak, 1921; Diplodina acerina (Passerini) Sutton,1980.
