Abstract A description is provided for Phyllachora eleusines. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Eleusine coracana, E. floccifolia, E. jaegeri, E. multiflora, Eragrostis amanda, E. braunii, E. curvula, E. superba (Gramineae). Unconfirmed records from a number of other species of Eleusine and Eragrostis. DISEASE: Tar spot of finger millet and related grasses. DISTRIBUTION: AFRICA: Ethiopia, Kenya, South Africa, Uganda, Zaire. NORTH AMERICA: USA (Alabama, Georgia, Nebraska, New Mexico, Texas). SOUTH AMERICA: Argentina, Brazil, Uruguay, Venezuela. AUSTRALASIA: Australia. TRANSMISSION: Not studied in detail, but morphological features agree with those of relatives which have been shown to disperse ascospores actively via air currents, possibly with secondary dispersal via water splash.
