Calvatia oblongispora

Calvatia oblongispora is a species of puffball from the genus Calvatia. Found in Brazil, it was described as new to science in 2009. The fruitbody is spherical or nearly so, measuring about 8 – in diameter. The thin, fragile peridium is readily detachable from the internal gleba. It is light beige and wrinkled, with a small, short, thin mycelium cord up to 5 mm long. The spores are cylindrical to ellipsoid in shape, hyaline (translucent), and measure 5.4–7.5 by 3.6–4.3 μm. They are covered in small spiny protrusions and have a single oil droplet within.
