4. n. A subterranean fungus, Pachyma Cocos, otherwise known as Indian bread, Indian head, and Indian loaf, found widely in the southern United States. It grows in light loamy soils on old roots as a saprophyte, or perhaps a parasite. Its size, form, and barklike exterior give it the outward appearance of a cocoanut; within it presents a compact white mass without apparent structure. When first taken from the ground, it is moist and yielding; but in drying the white substance becomes very hard, cracking from within. It is entirely tasteless, insoluble in water, without starch, and is composed in large measure of pectose.
