Conidiophores are usually erect, upright, or flexuous; normally simple but occasionally branched; septate, and very slightly inflated at the end.
Meristematic apices in conidiophores can produce conidia in a basipetal sequence and can create separate chains.
Conidiophores are separate from vegetative hyphae until the first conidium gets produced.
The meristematic apices of those said conidiophores do not appear to extend much during spore development, which gives legitimacy to meristem arthroconidia.
Retrogressive conidial development occurs when the conidiophore gets smaller since each conidium forms.
The unique basipetal catenulate conidiophores cluster, as well as the asymmetric basal cell of both the conidium and the unique basipetal catenulate conidiophores cluster, are essential diagnostic features in recognizing a variant pertaining to the genus Trichothecium.
