Hypoxylon deustum: The chromosome number

  • Published:
Mycopathologia et mycologia applicata Aims and scope Submit manuscript

Summary

The haploid chromosome number ofHypoxylon deustum is 4. Ascospores are uninucleate when formed, becoming binucleate shortly thereafter. One of the two nuclei disappears in maturing ascospores. Mature ascospores are apparently uninucleate. The significance of these and other findings to the taxonomy of the fungus is discussed.
