Study finds lucky charms don't work

This had been assumed to be tinder, but this particular fungus is not very flammable, and is not an effective tinder.

Does anyone know the name of a famous short story? A man is lost in the woods and knows that he is going to freeze to death if he can't make a fire. He tries and tries and finally lights it. But the heat from the fire rises up and loosens some snow from a tree above, which fall down to snuff the flames.
