Abstract A description is provided for Phyllachora sacchari. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Polytoca macrophylla, Rottboellia exaltata, Saccharum officinarum, S. aegypticum, S. robusta, Sorghum almum, S. bicolor, S. halepense, S. sudanense, S. vulgare and S. vulgare var. saccharatum. DISEASE: Causes tar spot or black spot on leaves. This disease has so far not been reported to be serious. However, in severe cases, leaves dry up (Tarr, 1962). GEOGRAPHICAL DISTRIBUTION: Asia (Bangladesh, India, Malaysia (W. Malaysia, Sabah), New Guinea, Philippines); Europe (Sicily); Africa (Nigeria); S. America (Argentina). TRANSMISSION: Although none has been reported, it appears probable that the ascospores present in the crop debris may act as source of primary infection. The ascospores may also be disseminated by wind or rain.

Abstract A description is provided for Venturia pirina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Principally on pear (Pyrus communis) and other Pyrus spp., also recorded from Eriobotrya japonica (loquat) (Herb. IMI). DISEASE: Causes scab or black spot of pear, which results in loss of quantity and quality of fruit. The disease attacks shoots, buds, leaves and fruit, symptoms and aetiology being very similar to those of apple scab caused by V. inaequalis on Malus spp. (CMI Descript. 401). Dark, more or less circular scabs are produced on leaves and fruit, often with some growth distortion. Infection of young wood is more common than with apple scab and causes pale brown blister-like lesions which burst to release conidia in the following year. GEOGRAPHICAL DISTRIBUTION: Worldwide in temperate and subtropical regions wherever pears are grown (see CMI Map 367, ed. 2, 1968). TRANSMISSION: Epidemiology is similar to that of apple scab. The overwintering saprophytic perithecial stage on leaf litter releases airborne ascospores in spring which infect young growth, and secondary infection by conidia dispersed during wet summer weather also occurs. Overwintering lesions on young wood are more frequent than with apple scab and conidia produced by these in the spring can be an important source of primary infection (46, 2061; 47, 849).

Abstract A description is provided for Phyllachora pterocarpi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pterocarpus angolensis, P. brenanii, P. erinaceus, P. indicus (syn. P. pallidus), P. rotundifolius (syn. P. sericeus), P. tinctorius (syn. P. chrysothrix). DISEASE: Tar spot of leaves. GEOGRAPHICAL DISTRIBUTION: Brunei, Ghana, Guinea, Malawi, Malaysia, Mozambique, Nigeria, Papua New Guinea, Philippines, Sierra Leone, Singapore, Solomon Islands, South Africa, Tanzania, Togo, Zambia, Zimbabwe. TRANSMISSION: Almost certainly by air dispersal of ascospores, though no research is known. The conidia are almost certainly spermatial in function.

Abstract A description is provided for Acroconidiella tropaeoli. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Tropaeolum spp. DISEASE: Causes severe losses in nasturtium seed fields in coastal California. It produces a yellowing and death of the leaves after mid season and this reduces yield. The fungus occurs sometimes on stems and is present on seeds but is most abundant on leaves where it forms characteristic irregular or subcircular brownish or purple spots visible on both sides. These are up to 1 cm diam. or often larger through confluence, the centres later shrivel and the surrounding tissues may form a broad yellow margin. GEOGRAPHICAL DISTRIBUTION: Argentina, Australia, Ceylon, Ethiopia, Guatemala, Haiti, India, Jamaica, Kenya, Mauritius, New Guinea, New Zealand, Tanzania, Uganda, U.S.A. TRANSMISSION: The pathogen is borne internally and externally in up to 93% of commercial nasturtium 'seed', persisting for at least 3 years in the form of thick-walled mycelium in the pericarp and seed.
