The reproductive organs of lichens are ascocarps or basidiocarps. Sexual reproduction of lichens also occurs through plasmogamy. Male genitalia of lichens are called spermagonia and female genitalia are called carpogonia. Spermagonium produces pungametes and carpogonium produces strigametes. The male gamete and female gamete unite to form the zygote. The zygote germinates to form a new lichen.
