We present new evidence for early asymptomatic infection of flowers of olive varieties Barnea and Manzanillo by Colletotrichum acutatum J.H. Simmonds and C. gloeosporioides (Penzig.) Penzig & Saccardo, in Australia. Incubation of the surface-sterilized flowers showed that they were infected from early stages of flowering until fruit set and that the fungi were present in calyx, petals, stamens and pistil. In some instances the pedicels were also infected.
