Coal is a combustible black rock that is formed from prehistoric plant remains. Coal is formed from the anaerobic decomposition of dead plant matter such as trees, ferns, mosses and other marsh plants that grew on the earth surface over millions of years ago. Coal is composed largely of carbon and is usually burned as a fuel.
The sporophore is the umbrella-shaped body of the mushroom. It
is also called the "fruit" of the fungi. It starts out as a small
button and grows into stalk and cap. The cap becomes larger and unfolds like an
umbrella.
