It is saprophytic if i am not mistaken.

Saprophytic means: it eats dead plants. Necrotroph means: it kills a plant, and then eats the dead plant.

I have heard the term saprophytic many times, always related to fungi, but it's the first time i have heard the term necrotroph. My browser's spell correction underlines it with red like a word not spelled right. It is probably a new term.
