Although the actual fruit bodies are infrequently seen, the green staining of wood caused by the fungus is more prevalent.
The green colour corresponds to a form of the dye with no net overall charge. In neutral media (pH 7), only the nitrogen atom of the diphenylamine moiety carries a positive charge and the blue dye molecule is an anion with an overall charge of −1. The pK a values for the losses of the two protons are 1.15 and 1.82, respectively.
