Asexual reproduction by sporangiospores
Sexual reproduction by gametangial contact or gametangial copulation.

Asexual reproduction by conidia
Sexual reproduction by somatogamy and gametangial contact.


Basidiomycetes:
Branched, septate with dolipore septum.
Asexual reproduction not found.
Sexual reproduction by somatogamy and spermatization.


Deuteromycetes:
Septate and branched mycelium.
Asexual reproduction by conidia.
