The process of reproduction in Fungi can occur simply through body parts (Vegetative) or by formation of haploid Asexual Spores (Asexual Reproduction) or by formation of gametes and sexual spores (Sexual Reproduction) .
The Fungi group produces several types of Asexual Spores. These spores are mostly haploid spores and are formed by mitotic divisions in the Haploid body of Fungi. Thus, these spores are also called Mitospores.
Examples of Asexual Spores of Fungi
Zoospores
Sporangiospores
Conidiospores
Oidia
Chlamydospores
Let’s see the features of each type of spore
ZOospores
Endogenous spores i.e. Formed inside a closed chamber called Zoosporangia
Motile spores i.e. Flagella is present
Formed under favorable conditions
Thin walled spores
Present in members of the fungal class- Oomycetes (Phycomycetes)
Sporangiospores
Endogenous spores i.e. formed inside a closed chamber called Sporangia
Non-motile spores i.e. Flagella is absent
Formed under favorable conditions
Thin walled spores
Present in the members of the fungal class- Zygomycetes (Phycomycetes)
CONIDIOSPORES/ CONIDIA
Exogenous spores i.e. Formed outside the body
Non-motile spores i.e. Flagella is absent
Formed under favorable conditions
Thin walled spores
Present in the members of the fungal class- Ascomycetes
OIDIA
Exogenous spores
Non-motile spores
Formed under highly favorable conditions (sugar solution)
Thin walled spores
Present in the members of the fungal class- Ascomycetes
Chlamydospores
Exogenous spores
Non-motile
Formed under unfavorable conditions
Thick walled spores
Present in the members of fungal classes- Ascomycetes and Basidiomycetes
