Ascospores are formed in ascus under optimal conditions.. Typically, a single ascus will contain eight ascospores. Ascomycota · Ascus · Meiosis · Neurospora crassa · Saccharomyces.
Neurospora pannonica is homothallic, with 8-spored asci. mature the asci gradually become cylindrical, with the ascospores aligned in single file. of spores in the mature asci are typical of the genus Neurospora (Figs.
Ascospore ornamentation in N. crassa, hence the genus name Neurospora. four ascospores encloses two nuclei of opposite mating type; single-ascospore cultures The remaining mature asci show second-division segregation patterns .
