48、ous fungi from different taxonomic groups (ascomycetes, zygomycetes, and their anamorphic states formerly known as deuteromycetes or fungi imperfecti). They form a mycelium and spores by which they become visible macroscopically. Most spores are in the size range of 2 m to 10 m, some up to 30 m, and

49、 only few up to 100 m. Spores of some mould genera are small and become airborne very easily (e.g. Aspergillus, Penicillium) while others are bigger and/or embedded in a slime matrix (e.g. Stachybotrys, Fusarium) and less mobile.Mould spores are widely distributed in the outdoor environment and, therefore, occur in varying concentr
