A mushroom has no chlorophyll, no true stem, or roots.
Trees. Trees tend to grow much taller than grasses do because of their woody "stem" or trunk, which can hold a lot more weight than the stem of grass. Even bamboo, which is a type of grass, cannot grow as tall as most trees can.
The mushroom you are referring to is called the "shiitake mushroom." It has a long white stem and a dark brown or black top.
The portion of a leaf that wraps around the stem at the base of the blade on a grass plant is called the sheath. It helps to provide structural support to the leaf and connects it to the stem.
It is the stem or stalk that supports the mushroom's cap.
The top of a mushroom is called the Cap.I think it is the cap, or the dome.cap
The stem
It's technically a stem but grows underground and can give rise to all the other needed plant parts. It's even referred to as a rootstem at times.
The stem of a mushroom is called the stipe. It is the elongated structure that connects the cap (pileus) of the mushroom to the mycelium in the ground. The stipe provides support for the cap and helps transport nutrients within the mushroom.
Possibly bamboo. Bamboo can grow 6 to 8 inches in diameter, but bamboo is considered to be a grass, and each bamboo log a "stem".
