MoldBASIDIOSPORES – One of the major classes of fungal organisms. This class contains the mushrooms, shelf fungi, puffballs, and a variety of other macro fungi. They are agents of wood rot, which may destroy the structure wood of buildings, and have the potential to produce a variety of toxins. Members of this family produce type I and III fungal hypersensitivity reactions. It is extremely difficult to identify specific genera of mushrooms by using standard culture plate techniques. Some basidiomycete spores can be identified by spore morphology, however; some care should be exercised with regard to specific identification. Spores disseminate during rain or in times of high humidity. These are rarely reported as opportunistic pathogens.
