What kind of fungus is the woody white fungus that rises on the trunk?

The white woody mushroom that grows on the trunk of the tree is not a mushroom, and it is good to grow this fungus on rainy days, so you can't eat it.

**I don't see it very clearly, no matter what kind of fungus it is, as long as you don't know it, don't use it indiscriminately. Many bacteria are poisonous and can easily cause food poisoning.

This should not be clear, and there are sometimes a lot of these fungi, which may only be known through laboratory tests.

I'm sure many of you will see a layer of white cotton on the branches of trees or hedges, right? It is firmly covered on the branches of the plant, which not only has an impact on the beauty of the plant, but also has a great impact on the growth and development of the tree, and may lead to the death of the whole plant in severe cases. So what the hell is this?

In fact, it is a scale insect, and today, Xiaoba will introduce to you a scale insect - Mulberry white shield scale.

1. Host and harmful characteristics.

Mulberry white shield scale mainly harms peach, plum, pear, apricot, plum, mulberry and other fruit trees and garden plants. The mulberry white shield scale strains in groups of nymphs and female adults in 2 to 5-year-old branches to suck sap. The distribution trend of the insect on trees was more in the upper part than in the middle, more in the middle than in the lower part, more in the shade than in the sun, and more in the branches than in other places.

The shells of the severely damaged plants are densely overlapped, as if covered with a layer of cotton wool, which seriously weakens the tree and makes the damaged branches stunted. Generally, the upper branches and leaves of the affected plants begin to shrivel, turn yellow, and dry up, and then spread to the middle and lower parts, resulting in the death of the whole plant.

This should be a tree tongue Ganoderma lucidum, a variety of Ganoderma lucidum, also known as Pinggai Ganoderma lucidum fruiting body perennial, laterally sessile, woody or near-wood plug. cap flattened, semicircular, fan-shaped, flat hill to low horseshoe-shaped, (5-30) cm (6-50) cm, 2-15 cm thick; The cover skin shell is grayish-white to grayish-brown, often covered with a layer of brown spore powder, with obvious concentric ring edges and rings, often with wart-like protrusions of different sizes, and often irregular fine cracks after drying; The capped margin is thin and sharp, sometimes obtuse, entire, or wavy. The nozzle surface is initially white, gradually turning yellowish-white to grayish-brown, and the injured area immediately turns brown; The nozzle is round, 4-6 per 1mm; The tubes are multilayered, with a thin layer of hyphae sandwiched between the tubes, and the old tubes are filled with white powdery mycelium.

The spores are oval, with a truncated wall bilayer at one end, the outer wall is smooth and colorless, and the inner wall has spiny protrusions, brown, (.

Tree tongue Ganoderma lucidum is also known as flat cover Ganoderma lucidum, tree tongue flat Ganoderma lucidum, old mother fungus, maple fungus, old cow dry, etc. The fruiting body is large or extra-large. Sessile or almost sessile.

The cap is semicircular, oblate hemispherical or flattened, the surface is gray, gradation brown, with concentric annular ridges, sometimes nodules, epidermis and thin margins. The flesh is light chestnut and the mycelium is round. It is born on dead standing trees, fallen trees and felled stumps of broad-leaved trees such as poplar, birch, willow and oak.

It is one of the important wood-rotting fungi. Causes the xylem of wood to form white decay. Can be used medicinally.

It is used as an anti-cancer drug in China and Japan. It can also treat rheumatic tuberculosis, and has the effects of relieving pain, clearing heat, dissolving accumulation, stopping bleeding and dissolving phlegm.

Ganoderma lucidum is a fungal molecule in the natural ecology, which, together with many fungi, plays a pioneering role in decomposition, and is an important link in the material cycle and energy transformation of forest ecosystems. Ganoderma lucidum is an important medicinal resource given to human beings by nature, and as a medicinal fungus, it plays an important role in human diseases. Ganoderma lucidum is a large fungus in the fungal world, it grows into a huge volume, grows in a variety of forms, and can become the object of people's appreciation without carving.

The mouth surface of the fungus tube of Ganoderma lucidum is generally gray-white when it is fresh, and if it is carefully protected, it is a natural canvas for artistic creation. The artistic depiction that takes advantage of the freshness and directness is very simple and natural because of the brown color of its mycelium. After the tree tongue Ganoderma lucidum is dried, it can still be as clean as white paper, and the color depiction carried out here will also be handy, ingenious, and achieve the perfect combination of the beauty of nature and the beauty of art, which is another wonderful thing in artistic creation.
