Green mould

Penicillium digitatum

It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or mould.

Initial symptoms include a moist depression on the surface which expands as white mycelium colonizes much of its surface. The centre of the mycelial mass eventually turns olive as conidial production begins. Near the end of the disease cycle, the fruit eventually decreases in size and develops into a empty, dry shell.
