An aspergilloma (or fungal ball) is a mass of fungus found inside the body, for example inside cavities such as the lungs or sinuses, or as abscesses in organs such as the brain or kidney. They are made up of threadlike fungal strands (hyphae) that are densely packed but only around 1/200 of a millimetre in diameter. A mass of hyphae is called a mycelium.
In this image, a slice through an aspergilloma has been imaged using a transmission electron microscope.
