Figure 1 Sexual structures and spores in A. nidulans. Nest-like fruiting bodies called cleistothecia (A) are constructed from hyphal cells and have associated globular Hülle cells that are thought to nurse the developing structure. Each cleistothecium may contain up to 100,000 ascospores (B) and these generally are the progeny of a single ascogenous hypha. Mature cleistothecia are typically 170 to 200 μM in diameter and ascospores are ∼5 μM in diameter. Photographs courtesy of Reinhard Fischer (University of Karlsruhe).
