Clinical laboratories are often challenged with mold identifica¬tion. In contrast with bacterial or Candida species, which are identified on the basis of biochemical properties, mold identifi-cation 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 identifica¬tion technique [4, 5].
