The mushroom is not the organism
A mushroom is a spore-bearing fruiting body. Most of the fungus is a mycelium you never see, and many fungi never make a mushroom at all.

Fruiting bodies
Fruiting bodies are spore-bearing structures: mushrooms, brackets, cups, puffballs, and many other forms. They are usually temporary relative to the mycelium that produced them.
More than cap and stem
Gilled mushrooms dominate popular imagination, but pores, teeth, smooth hymenia, and enclosed fruiting bodies are common. The hymenium is the fertile surface; learning that word unlocks keys faster than memorizing mascots.
Mushroom and toadstool
In English, toadstool is folk language, often hinting at danger or inedibility. It is not a taxonomic rank. Prefer characters — volva, spore color, substrate — over the folk label. See Mushroom and toadstool.
Cultivated consistency
Domesticated strains are selected for predictable fruiting. Wild fruiting bodies vary with weather and genetics. Oyster and shiitake kits teach different jobs because the organisms differ — not because one brand of box is morally superior.

FAQ
What is a fruiting body?
A spore-bearing structure produced by a fungus: mushroom, bracket, cup, puffball, and many other forms. It is usually temporary relative to the mycelium that built it.
Is “toadstool” a scientific category?
No. In English it is a folk word, often implying something inedible or poisonous. It is not a taxonomic rank. Prefer precise characters over the label.
Why do cultivated mushrooms look so consistent?
Domesticated strains are selected for predictable fruiting under controlled conditions. Wild fruiting bodies vary more with weather, substrate, and genetics.

Mushroom and toadstool
One language pair splits edible from suspect; another treats them as synonyms. How English got tangled — and why biology does not owe folklore a border.
Oyster and shiitake are different jobs
Pleurotus and Lentinula both fruit on domesticated blocks, but they ask different things of air, water, and patience. A kit sheet is not interchangeable.
