Diagnostic Notes
Morphology

Conidiophores up to 800 µm or more long, 3–6 µm thick, usually unbranched, septate, mid to dark brown, straight or slightly curved, usually without intercalary swellings but often swollen at tip and towards one side of conidiophore, conspicuous and thickened conidial scars at tip or sometimes at lower levels. Conidia small terminal conidia 2.5–6 × 2–3 µm, 0-septate, pale olivaceous brown, smooth or minutely roughened, cylindrical, ellipsoidal or subglobose; conidia are produced in branched chains and hence may have one or more, slightly protruding scars at either end. First formed conidia are cylindrical-oblong and longer, 2–41 × 3–4(–5) µm, 0(–1)-septate.

Cladosporium tenuissimum and C. cladosporioides are two quite common saprobic species isolated from numerous substrates. They are morphologically very similar and have, therefore, often been confused. However, they represent two morphologically, as well as phylogenetically allied but distinct species.
