General Structure and Shape:
The spores of Curvularia occur individually, with three or more transverse divisions, or septa. The shape of the spores is what is so unique to Curvularia, and in fact, is where we get the name. They usually have a curved appearance, having broad points at either end. Furthermore, the cell in the middle of the curve is often larger than those toward the end.
The spores are common in the atmosphere and tend to be especially important members of the air spora in tropical areas.
Although little is known about the actual allergenic proteins, it is assumed to be allergenic and also can be a cause of fungal sinusitis.
