Fusarium graminearum, which infects mainly corn, wheat and barley, produces trichothecene mycotoxins such as deoxynivalenol (DON) while Fusarium verticilliodes (recently renamed from Fusarium moniliforme) is mainly a maize (corn) pathogen, and produces compounds called fumonisins (see Figure 1).
Most prominent among these was that he die swiftly of his cancer, his lymphoma as it had been diagnosed, and for his small unholy soul to rise into an awaiting purgatory where he might lodge in eternity with all the arisen men he killed and the ones who had participated in the preparation of his own slow death by inhalation of Trichothecene mycotoxin instead of pure or poppied Laotian air, or whatever had blossomed badly inside him.
