Reasons for changing taxonomic name for fungi
|
Sexual stage was discovered and improperly described as different organism
Older name discovered (somebody named it first) fungus originally misidentified fungus reclassified based on genetic code classified by ribosomal ITS similar species are consolidated conglomerant of mushrooms divided into individual species |

Peasant farmers that traditionally grow cacao cannot afford |
|
Potato Cultivation
|
Brought back from S. America by the Spanish
Europeans at first refused to eat them because they believed in Doctrine of Signatures (thought potatoes caused tumors and growths) Grew well in rocky soil of Ireland gave to poor Irish peasants to eat and eventually the irish diet consisted of nearly all potato |
