The fungal organism Aspergillus ochraceous has popped up in several odd places during indoor air investigations. I have found it in steam tunnels, near potted plants and on carpet. The organism is capable of producing ochratoxin.
The organism can be confused with Aspergillus flavus because of the the rough stipe. But the yellow colony color and the uniformly biseriate head help differentiate this species. It grows well at 25 degrees Celsius
The organism has no specific identifying characteristics on an Air-O-Cell cassette. It would be classified as Asp/Pen like.
