Abstract A description is provided for Cercospora pappaea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Caricapappaea (pawpaw). DISEASE: Leaf spot of pawpaw. Leaf spots are circular at first, but become irregular with age, 3-10 mm diam., pale brown on the upper surface, indistinct on the lower. The fungus may also cause small shallow black dots on the fruit; these lesions may enlarge up to 3 mm, but do not cause fruit decay (Weber 1973).

Abstract A description is provided for Ophioceras leptosporum. Some information on its associated organisms and substrata, dispersal and transmission, habitats and conservation status is given, along with details of its geographical distribution (Africa (Cameroon), North America (Mexico), South America (Brazil (Bahia)), Asia (Afghanistan, China (Hong Kong), Malaysia, Papua New-Guinea, Taiwan, Thailand), Australasia (New Zealand), Europe (Belgium, Finland, Netherlands, Serbia, Spain, Switzerland, UK)). In a study of endophytes of Terminalia and other plants in Cameroon, Toghueo et al.

Abstract A description is provided for Entyloma calendulae f. dahliae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Dahlia variabilis, D. coccinia, D. pinnata; cultivated dahlia. DISEASE: Leaf spot of Dahlia. GEOGRAPHICAL DISTRIBUTION: Widely distributed in Europe including Finland and Sweden; Africa; North America (USA); Central and South America and West Indies (Argentina, Brazil, Colombia, El Salvador, Guatemala, Jamaica, Venezuela); Asia (Burma, India, Indonesia, Israel, Japan, Malaysia, Nepal, Pakistan, Sri Lanka, Papua New Guinea); Australia and New Zealand. CMI Map 114, ed. 4, 1983. TRANSMISSION: Soil-borne. Overwinters as ustilospores buried in plant debris; not transmitted by seed or in tubers, although spread by soil attached to tubers is possible (6, 97; 17, 655; 41, 603; 49, 1050); mature ustilospores are capable of remaining viable for a long period when dry (16, 304). Conidia contribute to dissemination during the growing season (49, 1050).
