Abstract

Deightoniella torulosa (Syd.) Ell. (syn. Brachysporium torulosum Syd.; Cercospora musarum Ashby ; Helminthosporium torulosum (Syd.) Ashby) has been recorded on banana leaves and fruits in most major growing regions (Commonwealth Mycological Institute, Kew, Surrey, Distribution Map No. 175). The majority of earlier references to this fungus have concerned a leaf disease known as ‘black-spot’1–3 and a blackening of the tips of banana fruits4,5.
