Abstract

Investigations on the development of conidiomata in Pestalotiopsis rhododendri (Saccardo) Guba were done by using light and Transmission electron microscopes. Light microscopic studies showed the presence of non-ostiolate, pycnidial conidiomata in culture. Acervular conidiomata are produced normally by species of Pestalotiopsis on leaves. The other interesting observation during the study was the ultrastructure of the conidial wall in the coloured cells as well as the basal and apical hyaline cells with the appendages. Pestalotiopsis rhododendri resembles P. uvicola in the development of conidiomata. The first time report of the various stages of development of conidiomata in Pestalotiopsis rhododendri will be useful in fungal systematic studies.
