Asexual reproduction occurs by the formation of asexual spores. The asexual spores are Sporangiospores or aplanospores, Conidia and Chlamydospores.
(i) Sporangiospores: They are endogenously formed spores in a sac like structure called as sporangia. Sporangia are borne on the special type of hyphae known as sporangiophores.
(iii) Conidia: They are exogenously formed non- motile spores borne on the specialized hyphae known as Conidiophores.
(ii) Chlamydospores: These are thick walled which are modified as resting spores. When favourable condition occurs it develop as new mycelia.
