| Contribution | Reported evidence of fungal causation of plant diseases. |
| Reference | Parris |
| Notes | The Tulasne brothers confirmed Prevost's 1807 finding of fungus as cause of wheat bunt and extended causation principle to other diseases. Fungal causation of plant diseases will receive little, if any, further consideration in this Timeline (the concept was scientifically established by this time, if not everywhere accepted). |
