Bennett confirmed and extended the observations and experiments of Gruby concerning the mycodermatous vegetations found in the crusts of the disease called Tinea favosa, or Zorigo lupinosa of Bateman; he announced the occasional existence of, and described, a plant found growing on the lining membrane or cheesy matter of tubercular cavities in the lungs of man. This was the first description of aspergillus (a pathogenic fungus) growing in the lung tissue of humans.
