Abstract: | The concept of a dangeardien is discussed in relation to the ascomycetous yeasts. In species of ascomycetous affinity the dangeardien may be expressed not only as the ascus, but also in the taxa showing an alternation of generation in the absence of an ascosporal state, as a site of reduction division. In such cases it is proposed to refer to the dangeardien as a meioconidiophore and to the externally delimited haplophase, as meioconidia. Taxa showing the formation of meioconidiophores are considered to represent perfect states. |
