Non-motile sperm cells called spermatia lack flagella and therefore cannot swim. Spermatia are produced in a spermatangium.
Fungal spermatia (also called pycnidiospores) may be confused with conidia. Conidia are spores that germinate independently of fertilization, whereas spermatia are gametes that are required for fertilization.
In some fungi, such as ''Neurospora crassa'', spermatia are identical with microconidia as they can perform both functions of fertilization as well as giving rise to new organisms without fertilization.
