Abstract A description is provided for Phyllachora bakeriana. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Known from Cassia fistula, C. hoffinanseggiana and C. inaequilatera. DISEASE: Causes a leaf spot of Cassia species. The disease is not significant in economic terms; it appears to be unsightly and not seriously damaging to the host plant. Little is known of its ecology. Being a tropical species it probably does not show marked seasonality, but ascomata seem to be most often mature in January or February. GEOGRAPHICAL DISTRIBUTION: Central America: Grenada, Jamaica, Puerto Rico. South America: Brazil; probably more widespread. TRANSMISSION: This has not been studied, but ascospores are probably dispersed in the air and directly infect leaves, in common with other Phyllachora species.

Abstract A description is provided for Diaporthe manihotis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Manihot esculenta. DISEASE: Leaf spot of cassava (46, 64) or sometimes referred to as Phomopsis blight of tapioca (54, 2588). In the early stages of infection the visible symptoms are pale green, watersoaked, small round spots on young leaves and petioles which rapidly enlarge and turn brown. Severe attack leads to defoliation and infection spreading to the stem. Affected areas become shrivelled with numerous pycnidia embedded in the tissue. On severely infected stems the bark starts to peel off gradually leading to partial or total girdling. GEOGRAPHICAL DISTRIBUTION: Africa (Ethiopia, Nigeria); Asia (India); Central America and West Indies (S.E. Dominica); South America (Colombia). TRANSMISSION: Probably by watersplash-dispersed conidia.
