What Types of Edible Mushrooms Are There? An Introduction to Common Varieties and Their Classification
Edible mushrooms refer to macrofungi with large fruiting bodies that can be eaten, commonly known as mushrooms. More than 350 species of edible mushrooms are known in China, and common ones include shiitake, straw mushroom, button mushroom...

Causes of Deformed Mushrooms in Agaricus bisporus and Their Prevention and Control Methods
1. Deformed mushrooms. When ventilation is poor and the carbon dioxide content in the mushroom house exceeds 0.3%, deformed mushrooms are likely to appear. If the fruiting position is too deep, mushrooms growing between the cracks of the coarse soil also tend to be deformed. The key to prevention and control is to pay attention to ventilation and air exchange in the mushroom house. 2. Red root mushrooms. Slightly acidic cultivation material, a high-temperature stage before fruiting, excessive water content in the casing soil layer, excessive application of glucose as a supplemental fertilizer, and poor ventilation in the mushroom house can all easily lead to red root mushrooms. The pH of the compost should be properly adjusted, the water content of the casing soil should be maintained at 22%-25%, watering should be avoided during high temperatures, and the concentration of supplemental fertilizer should be appropriate.

Prevention methods for thin-skinned mushrooms that open their caps early
Because the temperature alternates between cold and hot, the temperature varies greatly, and the day-night temperature difference reaches 10-15°C. When the mushroom house is ventilated excessively, or the temperature remains above 18°C for a long time, causing the mycelium to grow quickly and the mushrooms to fruit too densely, the fruiting bodies are prone to developing thin-skinned, cap-opening mushrooms with slender stipes, thin caps and early cap opening. Preventive measures: scientific management. Ventilate and spray water in appropriate amounts; when the weather changes suddenly, strengthen management and maintain suitable temperature and humidity in the mushroom house; during fruiting, the humidity should be kept at 12-16°C, and excessively dense mushroom buds should be removed appropriately.

Double mushroom showcase: two mushroom varieties each display their strengths
The Horticulture Research Institute of the Provincial Academy of Agricultural Sciences used single-spore hybridization, single-spore systematic selection and molecular marker-assisted selection techniques to breed the low-temperature-tolerant, high-quality, high-yield new brown button mushroom (Agaricus bisporus) variety "Zongxiu No. 1" and the new white button mushroom variety "Yingxiu No. 1", which have passed the first national batch of edible fungi variety certification. The new brown button mushroom variety "Zongxiu No. 1" has a cap surface of natural brown, with white stipe and flesh. The mushroom quality is excellent, the fruiting bodies are round and neat, the caps are thick and firm, and not sunken at the top; the flavor is delicious and the texture is tender. Because its cap is naturally brown, it requires no

Physiological Disorders of Mushrooms and Their Control Methods
Mushrooms are relatively sensitive to their environment. A poor cultivation environment will hinder their normal growth and development, produce various abnormal phenomena, and lead to reduced yields and lower quality. Common physiological disorders of mushrooms include excessive mycelial growth, hard opening of the caps, thin-skinned early opening, and the appearance of ground-button mushrooms and hollow-stem white-core mushrooms. They are described below: Symptoms of excessive mycelial growth: after the casing soil of the mushroom bed is watered, the fluffy mycelium of the mushroom will continuously grow toward the surface of the fine soil, and in severe cases will form a fine, dense, water-impermeable mycelial mat, thereby delaying the time of fruiting and reducing the

What causes mushrooms to have a thin cap skin and open their caps prematurely?
Symptoms: The fruiting bodies have thin stems and thin caps, and open their caps prematurely. Causes: Excessive mushrooming density, too high a temperature in the mushroom house, insufficient relative air humidity, overly dry casing soil on the bed surface, and rapid growth of the fruiting bodies can all lead to a thin cap skin and premature cap opening. Preventive measures: Appropriately control the mushrooming sites, ventilate the mushroom house in the early morning and evening, lower the temperature in the mushroom house, and appropriately increase the moisture of the casing soil on the bed surface and the relative air humidity.

Current Major Diseases of Northern Oyster Mushrooms and Their Control Techniques
1 Soft Rot Disease 1.1 Disease Symptoms The surface of the substrate or the mushroom bodies become covered with a layer of white cottony mycelial threads, fine and soft but growing very rapidly; the gradually infected mushroom bodies develop a light brown morbid condition spreading upward from the base of the stipe, and the mushroom bodies gradually soften and rot; about one week after infection, the mushroom bodies collapse on their own, or topple at the slightest touch, just like Chinese cabbage suffering from soft rot, but the soft-rotted mushroom bodies have no foul odor; mushroom bodies not yet soft-rotted grow extremely slowly, the caps gradually turn earthy yellow, lifeless and dull, clearly different from normal mushroom bodies; infected substrate no longer

Causes of Deformed Shiitake Mushrooms in Off-Season Cultivation and Their Prevention and Control Methods
The edible mushroom industry is an important part of agriculture. Vigorously developing the edible mushroom industry can not only promote a virtuous cycle of the ecosystem, but also increase farmers' income and improve agricultural efficiency, achieving an organic unity of economic, ecological and social benefits. With the development of the edible mushroom industry, although shiitake production ranks only second, the economic benefits it delivers should rank first. How to improve shiitake yield and quality is of great significance to the many practitioners in the field. In off-season cultivation of shiitake, deformed mushrooms often appear due to inadequate production management
