Fungi reproduce by vegetative, asexual and sexual methods
Sexual reproduction takes place in all groups of fungi except Deuteromycetes
Fungi may be monoecious (bisexual) or dioecious (unisexual)
Moneoecious species produce two sex organs (male and female) in the same thallus, thus they are called homothallic.
Dioecious forms produces sex organs in separate thalli, hence called heterothallic.
In sexual reproduction of fungi, the two compatible nuclei (male and female) are brought together by the following processes.
(1). Planogametic copulation
(2). Gametangial contact
(3). Gametangial copulatin
(4). Spermatization
(5). Somatogamy
