To accommodate new developments in clinical mycology, 22 organisms have been added to this classic text. The detailed descriptions of the thermally monomorphic molds are grouped according to culture characteristics rather than the expected site of infection (with the exception of the dermatophytes). An introductory page now precedes each group of fungi with a brief discussion and overview of the organisms that follow. The most dramatic modification to this edition is the incorporation of photomicrographs to complement the line drawings.
