A tinder that I have found to be plentiful in my area and usually dry enough to work with is the outer bark from a grape vine. It dries up and just sort of hangs on them in a fibery mass until it falls off. The best way to light it is to fluff it up by rolling a mass of it in your hands, then make sort of a birds nest out of it. I usually use charcloth or a match to light it. Once you get that stuff burning, you end up with a determined, smoldering, hot mass of fire really quick. It will even smolder long enough for you to go get some fuel if you have to. I usually light it, build the "framework" for my fire, then blow on it a few times. It lights the whole thing up every time.
Only mention it because it is a good alternative to dry grass and even better IMO.
