Abstract A description is provided for Pestalotiopsis theae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Camellia sinensis; also recorded on Cocos, Diospyros, Elaeis, Gossypium, Mangifera, Syzgium, Theobroma and a number of other unrelated hosts. DISEASE: Grey blight of tea, which begins as small brown spots on the leaves, later enlarging to 1 cm diam. or more and showing (on the upper surface) a greyish centre with light to dark brown margins. Lesions are usually circular or oval with concentric zonations marked out on the upper surface by the dark acervuli. On young leaves these zonations are often absent. Coalescence of the spots may occur. GEOGRAPHICAL DISTRIBUTION: Australia, Azores, Brazil, Burma, Ceylon, China, Canary Island, Ethiopia, Formosa, Ghana, Guinea, Hawaii, Hong Kong, India, Indonesia, Iran, Japan, Kenya, Laos, Malagasy Republic, Malawi, Malaysia, Mozambique, Nepal, Papua New Guinea, Peru, Rhodesia, Sierra Leone, Somaliland, S.

Abstract A description is provided for Rosellinia arcuata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Plurivorous; important on Camellia sinensis. DISEASE: Black root rot mainly of tropical and subtropical woody hosts; plurivorous but only of serious importance on tea (Camellia sinensis). The advancing edge of the mycelium is white, shading to black. On the root surface the black network of strands gives a woolly appearance and beneath the bark star-like fans of white mycelium spread out on the wood. On tea the fungus may spread up the stem fan a short distance; the bush often dies suddenly, the leaves remaining attached for some time. GEOGRAPHICAL DISTRIBUTION: Records of this fungus are apparently infrequent. It has been reported from Central African Republic, Hong Kong, India, Indonesia (Java, Sumatra), Kenya, Papua New Guinea, Sri Lanka, Zaire Republic. TRANSMISSION: As mycelium from surface organic litter and woody debris and possibly also through spores.

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. (2017) detected O. leptosporum and demonstrated that it produced amylase and lipase, both enzymes with potential economic applications.
