Plurivorosphaerella nawae (Hiura & Ikata) O. Hassan & T.H. Chang 2019
This fungus has been described from eastern Asia but has spread to Spain (first record in 2008). It causes "circular leaf spot of persimmon". Apart from the leaf spots the symptoms include chlorosis, premature defoliation as well as early fruit maturation and abscission. Older leaves are more seriously affected, while the spots are inconspicuous on younger leaves. Serious infections can result in total yield losses.
The fungus overwinters as sexual fruiting bodies (pseudothecia) in leaf litter. These eject their ascospores in spring which spread in the air, germinate on the leaf surface and cause the leaf symptoms after a long incubation period of several months. In autumn, pseudothecia develop on the back of the spots.
For a taxonomic analysis see Hassan & Chang (2019).
