Abstract A description is provided for Sphaceloma fawcettii var. scabiosa. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Rough and sweet lemon, lime, grapefruit, sweet orange, mandarin and satsuma orange, citron (Citrus medica), C. japonica and C. jambhiri. Sour orange somewhat resistant (McCleery, 1930) or immune (51, 2478). DISEASE: Tryon's scab or Australian citrus scab. GEOGRAPHICAL DISTRIBUTION: Australia (Queensland, New South Wales), S.W. Pacific (New Guinea, New Caledonia (41, 85), Fiji, British Solomon Islands); probably New Zealand (Jenkins, 34, 516), S.E. Asia (Malaysia, Hong Kong, Sri Lanka), Africa (Malagasy Republic and Comores Islands (51, 2478), Malawi, Rhodesia and Zambia); South America (Argentina (33, 292)). (From literature cited and specimens in Herb. IMI: CMI Map 161, ed. 2, 1966.)
