Phyllachora dalbergiae. [Descriptions of Fungi and Bacteria].
Abstract A description is provided for Phyllachora dalbergiae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Known from Dalbergia ferruginea, D. latifolia, D. nitidula, D. sissoo, D. stipulacea and D. variabilis. DISEASE: Causes a leaf spot of Dalbergia species. No research into the epidemiology or virulence of this disease has been carried out, but as the host genus is prominent and widespread it seems unlikely that serious damage is caused. In cases where the fungus is well established on the host, however, significant retardation of the growth rate must result. GEOGRAPHICAL DISTRIBUTION: Africa: Tanzania, Zimbabwe. Asia: Burma, India, Philippines. South America: Brazil. TRANSMISSION: This has not been studied, but it almost certainly occurs through the air-borne dispersal of ascospores in wind currents, which then directly infect the host leaves.
