Huh. I bought a bag of russett potatoes, and half of them are brown (or outright rotted) in the center. Nothing extending to the surface, rot that _starts_ in the middle.

Has potato blight jumped to russetts?

(All modern potatoes are monoclonal, it's just a matter of time. Panama fungus in bananas, blight in potatoes... Evolution came up with sex because monocultures are inevitably taken out by disease.)
