Ulocladium sp.: Contaminant. Isolated from dead
plants and cellulose materials. Found on textiles.
Rarely involved in disease.
Ustilago sp.: a genus in the smut fungi,
which are the Ustilaginales. The smuts are major
plant pathogens. There are no reports of human
infection. No information if available regarding
toxicity. Smuts have been documented as a cause
of Type I allergies (hay fever, asthma). Ustilago
is present in the air as dry brown spores (teliospores)
and will grow in culture as a yeast (basidiospores).
If viable Ustilago spores (dry, brown phase) are
isolated on culturable (Andersen) sampling, the
yeast phase will be the identifiable result. Natural
habitat includes grasses, cereal crops, weeds,
other fungi, and other flowering plants.
