Conidia grow from the tips of the translucent conidiophores. They are typically formed at the ends of specialized hyphae, the "conidiophores". They are typically formed at the ends of specialized hyphae, the conidiophores. They are generally produced from phialides on conidiophores by basipetal division. Microscopically, "Gliocladium" species produces hyphae, conidiophores, and conidia borne from hyaline phialides. The conidia have truncated bases and are on the tips of simple or branched conidiophores. Under these conditions, conidiophores excrete a milky substance of conidia. Catenate (in chains), dry conidia and an absence of differentiated conidiophores characterize Cladophialophora. Mycelium, and sometimes conidiophores and conidia were observed in the galleries as well. These are made up of conidia and conidiophores of the pathogenic fungus. "Purpureocillium lilacinum" forms a dense mycelium which gives rise to conidiophores. "F. solani" has aerial hyphae that give rise to conidiophores laterally. The pathogen then begins to produce its asexual conidia, either singly or on branched conidiophores. This is a cushion of conidiophores created from a pseudoparenchymatous stroma in plant tissue. Conidiophores and conidia are produced in the spring from sclerotial surfaces.
