Development and Cytology of Anixiella endodonta
Abstract
The homothallic fungus Anixiella endodonta exhibits typical sordariaceous centrum development. The ascocarp begins development as a coiled or looped ascogonium that becomes surrounded by hyphal branches. The surrounding hyphae produce the ascocarp wall and all the nonascogenous elements of the centrum. A cavity forms within the centrum. Paraphyses grow upward into the cavity prior to ascus formation and disappear as the asci enlarge. Crozier formation, ascus production, and cytology within the ascus follow the typical pattern. A diffuse diplotene stage is included. Unusually large spindle pole bodies are striking elements of the interphase II nucleus. The haploid chromosome number is six. The development and cytology of A. endodonia is compared with that of previously studied species of Anixiella and Gelasinospora. Similarities and differences indicate that the two genera are clearly related but are sufficiently distinct to warrant segregation.
