Abstract

SUMMARY: Nuclear behaviour and ascospore delimitation in was studied by light and electron microscopy. Electron-dense bodies occurred near nuclei at all stages from crozier formation to the development of young ascospores. It is suggested that these bodies be termed archontosomes. Asco- spores were delimited by the invagination of an ascus vesicle and the arch- ontosome-astral-ray complex participated in both the delimitation and orientation of the ascospores. The possible role of this complex in determining ascospore form is discussed.
