SUMMARY
The ascus initial is the binucleate penultimate cell of the crozier. The diploid nucleus in the ascus undergoes meiosis followed by two mitotic divisions. Delimitation of ascospore walls starts when the ascus contains 16 nuclei. The nucleolus persists up to metaphase of division I. Interphase stages after divisions I, II, and III are prominent. Normal arrangement of the ascospores in the ascus is linear. Occasional anomalous arrangements of ascospores have been interpreted as due to the misorientation of spindles during divisional stages. The haploid chromosome number for this species is 7 as observed from the chromosome configurations at diakinesis of division I and metaphase stages of divisions I, II, III, and IV. Initially the ascospores are binucleate but become uninucleate at maturity.
