Neurospora crassa
In heterothallic fungi, two different individuals contribute nuclei to form a zygote. Examples of heterothallism are included for "Saccharomyces cerevisiae, Aspergillus fumigatus, Aspergillus flavus", "Penicillium marneffei" and "Neurospora crassa". The heterothallic life cycle of "N. crassa" is given in some detail, since similar life cycles are present in other heterothallic fungi.
