EUDARLUCA-CARICIS, THE TELEOMORPH OF THE MYCOPARASITE SPHAERELLOPSIS-FILUM, ON BLACKBERRY RUST PHRAGMIDIUM-VIOLACEUM

Eudarluca caricis, the teleomorph of Sphaerellopsis filum, was found o n blackberry mst (Phragmidium violaceum) in south west England and its morphology is described. Cultures derived from ascospores produced py cnidial conidiomata and conidia typical of S. filum, confirming the co nnection between the meiotic and mitotic stages of the fungus. Microco nidia were also found in the cultures derived from ascospores. Conidio mata developed on the majority of uredinial pustules of P. violaceum 1 0 d after inoculating detached, uredinia-bearing blackbery leaves with the conidia from the cultures derived from ascospores.
