 The conidia produced are thin and curved with a whip-like shape.They have 13–20 septa, measure 65–135 by 2–3.5 μm, and usually have a single branch (typically about 45 μm long) that appears before cells are released.There are only a few species of Rhytismatales known to have anamorphs that do not function as spermatia (non-motile cells that function as a male gamete).
