Studies on Conidiomata developmental morphology of Pestalotiopsis disseminata

This study shows the conidiomatal development of Pestalotiopsis disseminata (Thuen.) Stey., using light and transmission electron microscope. Light microscopic study showed the presence of nonostiolate pycnidial conidiomata in culture, whereas it is known to produce only acervular conidiomata on leaves. Interestingly, the fungus showed the ultrastructure of the conidial wall in the coloured cells as well as the basal and apical hyaline cells with the appendages. P. disseminata was studied for the first time on the development of the conidiomata and conidia by light and transmission electron microscopes.
