Ulocladium sp. |
Mitosporic fungus. Hyphomycetes. | |
| Distribution | Where Found | Mode of Dissemination |
| Ubiquitous; cosmopolitan. Approx. 9 species. |
Soil, dung, paint, grasses, fibers, wood, decaying plant material, paper, and textiles. /span> | Dry spore. Wind. |
| Allergen | Potential Opportunist or Pathogen | Potential Toxin Production |
| Major. 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. |
