Summary Twenty one ascosporic species belonging to the genus Aspergillus were studied by using freeze microtome sectioning, light microscopy and scanning electron microscopy. Out of sixteen genera named on the basis of perfect states and their characters by various mycologists so far only eight were recognised in this paper. Some of the genera viz., Sclerocleista, Hemisartorya, Syncleistostroma, Harpezomyces, Sporophormis, Edyuillia and Sartorya which showed overlapping characters in the development, size of ascospores and their ornamentations etc., are reduced to synonymy. The genus Aspergillus comprises 132 species and eighteen varieties arranged in eighteen groups. Raper & Fennell (9) retained the generic name Aspergillus for both teleomorphs and anamorphs. However, later on sixteen different names based on the perfect states of Aspergilli have been proposed by various workers (5–7, 10,12) by revising some of the existing genera to accommodate the ascigerous states of Aspergilli. The major change in naming these genera probably started from Sarbhoy and Elphick (11) who created a genus Hemicarpenteles. Later on Subramanian (12) established several genera on the basis of perfect states. It appears that some of these are superfluous as their descriptions are either inadequate or overlapping. It was, therefore, thought desirable to make detailed comparative studies of these genera by using freeze microtomy, scanning electron and light microscopy.
