Conidiomatal development ofPestalotiopsis guepiniiandP. neglectaon leaves ofGardenia jasminoides

This study has clarified the conidiomatal development ofPestalotiopsis guepiniiandP. neglectaon leaves ofGardenia jasminoides. Acervuli ofP. guepiniiandP. neglectadeveloped in a similar manner, in two stages. In the first stage, cells aggregated, the central cell of the aggregates gradually disappeared, and the cells of inner layer produced numerous conidia. This conidioma was pycnidium-like in appearance, and in some cases ceased development at this stage. In the second stage, the upper layer of the pycnidium-like structure broke open, forming an acervular conidioma.
