Cladosporium is the most common identified outdoor fungus. However their numbers greatly reduced in the winterand increase greatly in the summer. Cladosporium is also found indoors but at lower concentrations. Indoor Cladosporium species may be different than the species identified outdoors.

A Microbial Biorealm page on the genus Cladosporium
Classification
Higher order taxa
Eukaryota; Fungi/Metazoa group; Fungi; Ascomycota; Pezizomycotina; Dothideomycetes et Chaetothyriomycetes incertae sedis; Mycosphaerellaceae; mitosporic Mycosphaerellaceae
Species
Cladosporium elatum, Cl. Herbarum, Cl. Sphaerospermum, and Cl. cladosporioides
Description and significance
Cladosporium is found in the phylum Ascomycota. There are over 400 different species. Cladosporium is a pigmented mold most often found to be airborne or on rotten organic matter. It is found both indoor and outdoor. Some species may be resistant to certain types of treated lumber. Cladosporium appears gray to black or very dark green and can have a powdery appearance.
Genome structure
There has not been any research done to determine the genome sequence of any Cladosporium spp.
Cell structure and metabolism
The results of a study done by San-Blas Gioconda showed that the cell walls of Cladosporium were composed mainly of galactose, hexoses, and some mannose. However, chitin and melanin were not found in the cell structure.
Ecology
Cladosporium is the most common identified outdoor fungus. However their numbers greatly reduced in the winterand increase greatly in the summer. Cladosporium is also found indoors but at lower concentrations. Indoor Cladosporium species may be different than the species identified outdoors. It is commonly found on the surface of fiberglass duct liner in the interior of supply ducts. A wide variety of plants are food sources for this fungus. It is found on dead plants, woody plants, food, straw, soil, paint and textiles. Produces greater than 10 antigens. Antigens in commercial extracts are of variable quality and may degrade within weeks of preparation.
Pathology
These fungi are the causative agents of skin lesions, keratitis, nail fungus, sinusitis, asthma, and pulmonary infections. Acute symptoms of exposure to Cladosporium are edema and bronchiospasms, and chronic exposure may lead to pulmonary emphysema. More commonly, it is a more causative factor for intrinsic asthma.
