detecting type of generics within generics

I have a method which accepts many different types of objects for storage:

public void Store<T>(T item)
{
    // works fine
    if (item is Foo)
    {
      // ...
    }
    // works fine
    else if (item is Observation<ImageSignal>)
    {
      // ...
    }

    // isn't detected
    else if (item is Observation<Signal<ISpectrum>>)
    {
      // ...
    }

    else 
    {
      // Observation<Signal<ISpectrum>> always hits this.
      throw new NotSupportedException();
    }
}

Can anyone tell me how I can detect this?

EDIT: I was actually passing in an object which wraps this object. Eric was right. Problem solved. Thanks for the quick responses, however.

In this case wouldn't it be better to overload the Store function? It would be much easier to follow the logic.

public void Store(Foo item)
{
}

public void Store(Observation<ImageSignal> item)
{
}

public void Store(Observation<Signal<ISpectrum>> item)
{
}
