Summary

Nuclear behavior during ascosporogenesis ofSordaria sclerogenia Fields and Grear was studied with the use of the HCl-Giemsa staining technique. Except for some spore abortion and occasional irregular mitotic divisions in the spore, the chromosome behavior was found to be compatible with that reported for other members of theSordariaceae and other pyrenomycetes with eight linearly arranged ascospores. A haploid chromosome complement of seven was found. The behavior of the centriolar-bodies during meiosis in this organism is discussed.
