Laboratory Notes
Growth/Culture Characterisics
Grows well on general fungal media. White, floccose, spreading. Develops brown to black spore clusters with time.
Spore Trap Recognition
Small, round brown spores. An equatorial germ slit may be seen with skill. Because spores land in "face" view on spore trap slides this slit is not as obvious as when spores are viewed from a culture.
Tape Lift Recognition
Distinctive and identifiable on tape lift samples.
