Synchytrium endobioticum: Potato Wart disease or Black Scab

By USDA-APHIS-PPQ [public domain]
Synchytridium endobioticum

Synchytrium endobioticum is a chytrid fungus (chytridiomycota - other species of which are known for their part in amphibian decline, esp. toads; and also maize- and alfalfa-attacking species...)

It affects potatoes and other uncultivated plants of the Solanum genus.

The zoospores of Synchytrium infect suitable epidermal cells on the host.  The infected cells produce more zoospores, swell up, divide and surround the dividing zoospores... producing the characteristic wart.

Synchytrium endobioticum was added to the US Federal for agricultural plant pathogens: Public Health Security and Bioterrorism Preparedness and Response Act (June 12, 2002).
