Abstract A description is provided for Ramularia deusta. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Leguminosae: Lathyrus hirsutus, L. latifolius, L. maritimus, L. monatus, L. niger, L. palustris, L. pratensis, L. roseus, L. Silvester, L. sylvestris, L. tuberosus, Lotus corniculatus, L. siliquosus. DISEASE: Leaf spot of Lathyrus and Lotus spp. In the case of Lathyrus latifolius, perennial pea, lesions have been recorded on leaflets, petioles, stipules, tendrils, stems peduncles and pods (30, 41). Sporulation is known to occur in August and September. GEOGRAPHICAL DISTRIBUTION: Europe (England, Germany, Ireland, Sweden), South America (Brazil), North America (USA: California, Washington). TRANSMISSION: By wind dispersal of air-borne conidia. Baker et al. (1950) also noticed that lesions extended through pod walls infecting perennial pea seeds, but did not investigate this mode of transmission.
