Interpretation of Data Spore bearing structures are identified (when present) which presents a clearer picture of the extent of environmental contamination. These structures appear in various forms.  
  • Hyphomycetes (the Imperfect fungi) – common indoor contaminants which include such fungi as Aspergillus, Penicillium, Stachybotrys. Spores are produced on conidiophores. 
  • Ascomycetes (sac fungi) – produce spores from ascocarps (sac like structures bearing 4-8 spores). Examples are Chaetomium, Petriella, Ascotricha and others. 
  • Pycnidia (asexual fruiting body, often spherical or pear-shaped) – inside the pycnidia are found spores lining the cavity. When present in air samples, it is the only indicator of its presence. 
  • Basidiomycetes (mushroom fungi) – spores produced from a basidia; hyphae with clamp connections are detectable in the air.
