Hendersonula toruloidea. [Descriptions of Fungi and Bacteria].
Abstract A description is provided for Hendersonula toruloidea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On a wide range of hosts including Acacia spp., Agave sisalana, Ananas comosus, Arachis hypogaea, Citrus spp., Dioscorea spp., Ficus carica, Furcraea spp., Hevea brasiliensis, Ipomoea batatas, Juglans regia, Juglans hindsii, Malus pumila, Mangifera indica, Manihot utilissima, Melia azedarach, Morus alba, Musa spp., Liriodendron bipinnatifidum, Pithecolobium dulce, Plumeria acutifolia, Populus alba, Prunus spp., Psidium guajava, Sansevieria spp., Solanum tuberosum, Trifolium alexandrinum, Trigonella spp., Vitis vinifera (Browne, 1968 and Herb. IMI). Also pathogenic to man (Gentles & Evans, 1970). DISEASE: On plants: Causing branch wilt of fig, grapevine and walnut; dieback of apple, grapefruit, mulberry, stone fruit and walnut; canker of grapefruit, mandarin orange and mulberry; gummosis of apple, fig, grapefruit, mandarin orange, poplar and walnut; fruit rot of Cavendish banana and orange (on inoculation); associated with a rot of potato tubers (Solanum tuberosum) in U.K. following inoculation with roots of potato naturally infected with Phoma exigua (Herb. IMI) and a storage rot of yam (Dioscorea spp.) in Nigeria (45, 3254). On man: The fungus has been isolated in U.K. from infections of feet and/or toe-nails of former residents of the tropics (Gentles & Evans, 1970). GEOGRAPHICAL DISTRIBUTION: Africa (Ghana, Guinea, Nigeria, Rhodesia, Sierra Leone, Sudan, Tanzania), Asia (Cyprus, India, Iraq, Malaysia, Pakistan); North America (U.S.A. : California); Central America and the West Indies (Jamaica); Europe (U.K.). TRANSMISSION: By wind-borne spores. A wound parasite of fig (43, 2007), grapefruit (34: 365), grapevine (46, 2590), mulberry (35: 647) and of banana and orange fruit (43, 1716). Germinating conidia penetrate walnut branches only through breaks in the periderm (43, 884u) especially cracks caused by sun scorch (35: 495; 44, 1757b). Hail damage also predisposes fig to branch wilt (43, 2007).
