Characteristics: Growth/Culture Notes on Spore Trap Recognition Notes on Tape Lift Recognition
Grows on all general fungal media, forming small, mounded, delicate colonies. Not distinctive. Small one-celled, colorless spores. May be counted as Penicillium/Aspergillus, or "other colorless." Due to their small delicate nature, they may be missed. Occasionally found on tape lifts. Optical resolution through tape is sometimes inadequate to identify the delicate structures of Beauveria.
