WebSoon eight ascospores are delimited centred around the nuclei in the ascus which is again developed from the ascus mother cell (Fig. 194H). A slightly complex situation is exhibited by the genus Spermophthora where a short ascogenous hypha is formed from the top of which the ascus is developed.
WebEight haploid ascospores are produced within each ascus. The fully formed ascospores are oval, unicellular and hyaline. When they become mature, each ascus opens explosively by a lid and the spores are shot out in a jet of liquid. Each spore under favourable conditions, germinates and forms a new mycelium.
