Abstract

The life cycle of Ascosphaera apis (Pericystis apis) is described. The fungus is morphologically heterothallic (sexually dimorphic). An ascogonium with a trichogyne, nutriocyte, and stalk-like portion is recognized. There is no antheridium. An ascogenous system with croziers and asci is formed within the nutriocyte. It is thought that each ascus produces eight spores. The mature asci are tightly grouped together as spore balls. The taxonomic treatment of the Ascosphaeraceae as a family within the Eurotiales is discussed.
