Codinaea fertilis was consistently isolated from roots of ladino clover ‘Tillman’ in Wake County, NC. In 10 samples from four locations, C. fertilis comprised 6.1–29.1% of isolates obtained from clover roots. Isolates of C. fertilis were grown on cornmeal and sand medium and incorporated into pasteurized or field soil in two greenhouse studies. A light to dark brown surface necrosis developed on many tap roots and fibrous roots within 9 wk of transplantation into infested soil. C. fertilis was consistently reisolated from symptomatic roots and from some healthy roots but was not isolated from plants grown in noninfested soil. C. fertilis has not previously been reported in the United States.
