1. Stipe empty. Mushrooms appear to be normal from the outside, but they are cut off and the stipe is found to be partially hollow. There is usually an annular cavity around a hard core. Later, the stipe of the stipe may be cracked and then rolled back, making the appearance of the mushroom poor, and its commercial properties declining.
Reasons: This is mainly due to the low humidity of the air during the mushrooming period, the rapid evaporation of water from the mushroom body, the dryness of the soil layer, and the lack of moisture in the fruit body.
2. Stipe cracking. The vertical cracking of the stipe is sometimes accompanied by horizontal cracking, which causes the splinters of the stipe to curl up and down.
Reason: Due to Mr. Mushroom's length in a very moist covering soil, and then after the cover soil dries, then quickly increase the humidity of the cover soil to induce the formation of cracking symptoms.
3. Stomach enlargement. Occasionally, the swelling of the mushroom's stipe may be visible, possibly at the base, middle, or apex of the stipe.
4. Hard folds. Open umbrella mushroom. From the bottom up, the color is pale, and the pleats are shallow or absent. If the cap is broken, the cap usually appears thicker than usual.
5. Ugly mushrooms. The differentiation of fruiting bodies looks ambiguous and often related to the first tidal mushroom in autumn. Not normal development and become a variety of Ugly Mushrooms, from the shape of the tumor until the shape of the fruit body is still distinguishable, but the mushroom cover is oddly shaped. Individual sub-entities may also be linked together.
6. Water stains. Mushrooms have symptoms that are clearly visible in the influent area, especially in the stipe. If the mushroom is squeezed and squeezed, it will produce water; and sometimes mature fruiting bodies will spontaneously flow out of a large number of clear or colored liquids and then rot.
7. Impartial rot. Symptoms are similar to dry rot, but can restore growth and produce normal fruit bodies. It is caused by excessive water spray for a long time.
8. Mushrooms into a bundle. Produce a large number of nailhead mushrooms, basically can not grow up. This is due to the fact that the environment is too conducive to the formation of mushroom buds.
9. mushrooms into a group. Mushroom clustering refers to the occurrence of mushroom piles, which are related to the cyclical low temperatures that occur during the formation of mushroom buds.
10. Fungi. When the mycelium grows through the soil, a thick layer of white hyphae grows on the surface of the soil. The bacteria was impervious and the mushrooms were hindered. This is due to high concentrations of carbon dioxide coupled with high humidity and high temperatures. Remedies In addition to adjusting the environmental conditions, the bacteria were immediately lightly sterilized and re-covered.
11. Mushroom death. It usually appears later in the mushroom tide, and the soil covered with the bacteria is good, but the buds are dead and produce a mushroom-free community.
Reason: Usually caused by the presence of water-impervious mycelial layer in the cover soil, causing the surface of the cover soil to be soaked. Contrary to bacterial infections, the cause is the lack of early water spray of mushrooms, which allows dense mycelium to colonize dry soil.
12. With soil mushrooms. When mushrooms come out of mushrooms in too deep soil, they are often covered with earth.
Cause: When the mushroom is wrong or the surface of the cover soil is dry, it causes deep fruiting.
13. The mushroom body scales. The upper surface of the mushroom body tilted.
Causes: The natural reaction to air drying or the pentachlorophenol sodium fume caused by the mushroom bed.
Types of mushroom physiological abnormalities
Mushroom malformations occur mostly due to temperature differences or unfavorable environments; they may also be related to the strains that they cause. The common deformed mushrooms are mainly the following:
