|Distribution||Where Found||Mode of Dissemination|
Approx. 9 species.
|Soil, dung, paint, grasses, fibers, wood, decaying plant material, paper, and textiles.||Dry spore.
|Allergen||Potential Opportunist or Pathogen||Potential Toxin Production|
Type I allergies (hay fever, asthma).
Ulocladium cross-reacts with Alternaria, adding to the allergenic burden of Alternaria-sensitive patients.
|Rare subcutaneous tissue infection.||Not known.|
|Growth Indoors||Industrial Uses||Other Comments|
|Widespread. Found on gypsum board, paper, paint, tapestries, jute, other straw materials. Ulocladium has a high water requirement.||Not known.||None.|
|Characteristics: Growth/Culture||Notes on Spore Trap Recognition||Notes on Tape Lift Recognition|
|Grows well on all general fungal media. Colonies are dark brown to rusty brown, granular to velvety. Geniculate sporulating structures can be observed with the stereoscope.||Distinctive brown spores. Young spores or spore fragments may be confused with Alternaria, Pithomyces, and others, although Alternaria usually has shades of olive green pigment.||Distinctive, readily identifiable on direct observation. Certain species may form rudimentary beaks and short chains which may be confused with Alternaria.|
