Is there any difference between the "autoignition temperature" and the "ignition temperature" of a substance?

The autoignition temperature is the lowest temperature at which a substance can spontaneously ignite in a normal atmosphere without an external source (spark,flame etc).
"Ignition temperature" is what people call autoignition temperature who don't care about details. As Ivan said, there is no such thing as ignition temperature.
