It is noteworthy that the structure of the fungus body confers an enormous surface area.
Sexual reproduction is via conjugation , in which hyphae from different mating types fuse.
The life cycle of Neurospora , which has been studied extensively, illustrates this phenomenon. Mating types are genetically dissimilar but can form either male or female structures- hence, they are not different sexes. Note that there are no sperm with motile flagella in any of the fungal life cycles. Diversity of Fungi There are about 100,000 spp. of fungi within three major taxa. Classification is based on the sexual structures exhibited.
