Abstract A description is provided for Hypoderma rubi . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: This species has been reported on leaves, petioles and twigs of a wide range of woody plants, mostly dicotyledons, but even including one species of conifer. The principal host, however, and the one on which it is most commonly collected, is Rubus . DISEASE: Hypoderma rubi usually fruits only after the apparently normal senescence and death of the host plant, but on Rubus idaeus and related species ascocarp initials are occasionally found developing on current year's living floricanes in pale spots surrounding the point of peduncle attachment. The fruit on affected panicles is frequently then aborted, and it has been surmised that in these cases the fungus enters the biennial cane at the end of the first season through the petioles of senescent deciduous leaves. GEOGRAPHICAL DISTRIBUTION: Widespread in Europe and North America, apparently also occurring in temperate South America and Asia. TRANSMISSION: By air-borne ascospores in wet or humid weather.
