Other Comments


Potential Health Effects


Type I allergies (hay fever, asthma).
Other: A relatively common cause of allergic fungal sinusitis.

Potential Opportunist or Pathogen

Laboratory Notes

Growth/Culture Characterisics

Grows well on general fungal media; most isolates need "light/dark cycling" for sporulation. Colonies are shades of gray to brown.

Spore Trap Recognition

Distinctive; large second or center cell gives conidia pronounced curved shape. Conidia from species with less pronounced curve may be misidentified. Some Drechslera spores are similar.

Tape Lift Recognition

Distinctive, readily identifiable on tape lifts.
