Abstract
The brown pigment produced byMadurella mycetomi has the capacity for condensation with itself or with organic material to form a complex which eventually becomes chemically intractable, and comprises the cement of the black grain in mycetoma cases. Such parts of it as allowed analysis suggested a glycoprotein, whose behaviour differed both from tannins and melanins.
