Neofabraea

Neofabraea (formerly known as Gloeosporium) forms a circular firm brown rot. It is also known as lenticel rot, and indeed the fungus may attack through a lenticel. The centre of the circle may be lighter coloured than the edge. The disease must be controlled in the orchard. Furthermore, storage conditions that slow down the ripening also slow down the onset of rotting. Consequently, this disease is usually found only after a storage period of at least several months.
