Recognized by sight: S. cepa is a very hard, tough gleba species. S. areolatum becomes quite powdery in maturity. There is also a difference in the peridium, but little to go on by the photos alone. In my experience, S. areolatum is typically the first Scleroderma to fruit in the summer (I have it fruiting in my back yard right now), while S. cepa is typically a later summer species, that often fruits only after heavy rainfall in August or later. Also, S. areolatum is quickly eroded away because of the thin peridium, while S. cepa can overwinter. I have it growing under my house – fruiting bodies which have been protected from rainfall that are more than a year old!
