title: Morphology of the rust fungus Puccinia boroniae revisited.
abstract: Puccinia boroniae Henns. is a rust fungus endemic to Australia, infecting various Boronia spp. This study describes and illustrates, using light and scanning electron microscopy, the telial stage, teliospore germination and basidiospore production of specimens collected from commercial Boronia plantations in Western Australia. Unusual formation of a single basidiospore per germinating teliospore, and the pycnial stage, observed on Boronia megastigma leaves, are reported for the first time for P. boroniae.
