The ascomycete fungus Claviceps purpurea is notable for causing ergotism, a severe condition. Based on the provided text, which of the following is NOT a characteristic symptom or outcome associated with ergotism?

  • A: Gangrene and burning sensations.
  • B: Nervous spasms and temporary insanity.
  • C: Hallucinations, due to lysergic acid, a precursor to LSD.
  • D: Significant decline in amphibian populations.

Explanation

The text attributes the 'decline or extinction of 500 species of frogs and other amphibians' to infections by chytrids Batrachochytrium dendrobatidis and B. salamandrivorans , not ergotism caused by Claviceps purpurea. Ergotism symptoms are distinct and affect humans/animals consuming infected rye.
