Hyphae mostly immersed, branched, septate, pale brown to dark brown, 2-6um wide; hyphae around the base of conidiophores generally wider and up to 9um wide.

Conidiophores produced singly or in groups of up to 10, erect, straight or flexuous, brown to dark brown for much of their length and brown to pale brown above; they are translucent throughout and the transverse septa can be seen. Conidiophores are 100-730um long, 7.2-10.5um wide just above the base which may be swollen up to 13um wide; they taper to 3.6-5.4um wide at the apex which can bear up to 17 percurrent proliferations.

Conidia almost entirely subspherical with a scar 3.6-5.4um wide on a short denticle, occasionally very slightly obovoid; the outer wall is c. 0.6um thick, brown and translucent permitting the thick (c. 6mm) hyaline inner wall to he seen. Conidia measure 17-30 x 15.5-30um.
