It is then necessary to induce sporulation to accurately identify the fungal pathogen.
Most fungi require moisture and high humidity to sporulate.
These conditions can be achieved by placing the sample in a moist chamber. Moist chambers can be simple such as a plastic bag or tupperware-like container. Place the sample in the bag or container with a moist paper towel. Mist the inside of the chamber using a spray bottle and seal the container. Do not make the moist chamber too wet because excess water can often reduce fungal sporulation.
