Clinical laboratories are often challenged with mold identification. In contrast with bacterial or Candida species, which are identified on the basis of biochemical properties, mold identification is largely based on phenotypic criteria. Related species or phenotypic variants may be misidentified and rare species may remain unidentified. As a result, molecular methods have been developed to overcome these problems, and comparative se¬quence analysis is now considered the gold standard identification technique [4, 5].
