Conidia are produced from the apex of an unbranched conidiophore. The typical "Trichoderma" conidiophore, with paired branches assumes a pyramidal aspect. Conidia develop laterally from pores beneath each conidiophore septum. These traits are characteristic of both types of conidiophore. The conidia are considered aleurioconidia because they arise singly at the apex of each conidiophore. To infect, it produces a conidiophore that then bears conidia. The phialides of the conidiophore are short and flask-shaped with distinct necks. The single-celled condia are borne in chains on the conidiophore tips. At these lower temperatures, sporulation shifts from conidiophore induction to conidial formation. "P. teres" (teleomorph "Drechslera teres") makes up to 3 conidia per conidiophore. The conidiophore is usually an asymmetrical, delicate structure with smooth, thin walls. Typically the conidiophore terminates in one or a few phialides.
