The [conidiophores](/source/conidiophores) are [dimorphic](/source/Dimorphic_fungi): there are microconidiophores and macroconidiophores. :The microconidiophores are reduced to conidiogenous cells (i.e. capable of generating [conidia](/source/conidia)) on hyphae that are erect, cylindrical, medium brown in color, smooth, with truncated ends and proliferating [sympodially](/source/Sympodial_branching). The conidiogenous cells appear at terminal or lateral locations on top of branched conidiophores; they are also medium brown in color, smooth and cylindrical, and also grow sympodially. :The macroconidiophores are erect, cylindrical, between straight and sinuous in shape, medium brown in color, smooth, and unbranched or branched only above.

The [hila](/source/Hilum_(biology)) are inconspicuous or somewhat darkened and thickened, and aren't [refractive](/source/refractive). There has been no observation of [chlamydospores](/source/chlamydospores). In particular, ''X. strelitziicola'' presents hyphae measuring 2–3 μm in width; microconidiophores measuring 4–7 x 2–3 μm; conidiogenous cells measuring 7–15 x 2.5–3 μm; macroconidiophores measuring 30–100 x 2.5–3 μm; and [conidia](/source/conidia) with [hila](/source/hilum_(biology)) that are 1-1.5 μm wide.
