Abstract

Pycnidia of Phaeomoniella chlamydospora (W. Gams, Crous, M. J. Wingf. & L. Mugnai) Crous & W. Gams (syn. Phaeoacremonium chlamydosporum) were found on Pinot Noir grapevines suffering from the disease known as black goo decline in a commercial vineyard near Geelong, Victoria. To our knowledge, this state of the fungus has not been seen in the field before, although it has been produced under laboratory conditions.
