bug or disease?

antonio85June 14, 2013

One of my tomato plant was dying, I saw a brown spot on the the stem. I tried to cut the stem and I found a black thing inside (picture attached). Does anyone have any idea of what it is?
Here you can find other pics of the plant https://plus.google.com/u/0/photos/103349177764416955212/albums/5889055300683946353?authkey=CNzS1uPTnYX04gE

Uh oh. A very nasty soil-borne fungus disease. Technical name Sclerotium rolfsii. Common names southern rot or timber rot.

Here's some info
