Conidium

Conidia, sometimes termed asexual chlamydospores, or chlamydoconidia 〔Jansonius, D.C., Gregor, Me., 1996. Palynology: principles and applications. American association of stratigraphic palynologists foundation.〕 are asexual, non-motile spores of a fungus, from the Greek word for dust, konis.〔(Conidium in the Collins Dictionary )〕 They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal.
Asexual reproduction in Ascomycetes (the Phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive of a specific species and can therefore be used in identification of the species.
The terms "microconidia" and "macroconidia" are sometimes used.
==Conidiogenesis==
There are two main types of conidium development:
* ''Blastic'' conidiogenesis, where the spore is already evident before it separates from the conidiogenic hypha which is giving rise to it, and
* ''Thallic'' conidiogenesis, where first a cross-wall appears and thus the created cell develops into a spore.
