The most prominent feature is the numerous microconidia formed along the hyphae or on short conidiophores which grow perpendicular to the originated hyphae. The microconidia are sessile (attached by a ‘base’ rather than a ‘stalk’). They can also be highly variable is shape ranging from pyriform (tear-drop) to clavate (club-like) to cylindrical and even larger round balloon-like forms. Macroconidia are usually rare and also show variation in shape & size from cylindrical to cigar shaped (10 – 65 µm by 4 – 12 µm). They are somewhat thick walled with a smooth surface and usually contain between 2 to 4 cells within each. Terminal and intercalary chlamydospores may also be present, particularly in older cultures. Another source[iii] has stated that spiral coils and arthroconidia may be present.
