Abstract A description is provided for Ramularia astragali. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Astragalus carolinianus. DISEASE: Leaf spot of A. carolinianus. The lesions are mainly circular, but occasionally fuse and become irregular.

Abstract A description is provided for Ramularia rubella. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Rumex acetosa, R. aquaticus, R. brownii, R. conglomeratus, R. crispus, R. hymenosepalus, R. longifolius, R. nepalensis, R. obtusifolius, R. pulcher, R. stenophyllus. DISEASE: Leaf spot of Rumex spp. Symptoms occur more frequently on older leaves. Spots are apparent on both sides of leaf. Lesions are irregular, frequently angular or circular, brown with a buff centre often having a dark brown or purple border, sometimes coalescent. Size varies from 1-15 mm (mostly 7 mm) diam. Sporulation begins at centre of lesion, conidia in profusion will give a frosted appearance to spots.
