(1) Harmful symptoms The mycelium of the pathogen is very similar to the mycelium of the edible fungus in the early stage of disease, and it is difficult to distinguish the two. However, when conidia are formed, Penicillium is a pale blue or green powder. After penicillium damages the mushroom bed and contaminates the culture material, it inhibits the growth of the mycelium of the edible mushroom so that it cannot form a fruit body, and even if it forms a fruit body, it will brown and rot.
(2) Morphological characteristics Mycelium is colorless or light-colored and separated. The erect conidiophores are bristles with symmetrical bifurcated or multibranched branches, with small stems at the top and conidiospores. Conidia are spherical or ovate, unit cells, smooth or rough surface, colorless, green or with other noise. The color of the colonies is green, yellow-green, blue, etc., and new white growth bands are common in the outer circle of the colonies.
(3) Occurrence Regularity Penicillium has strong adaptability, wide distribution, and a large number of conidia, and spores are transmitted through the air, soil, fertilizers, and plant residues. Penicillium is not only an important fungus of edible fungi, but also the main pathogen of agricultural products. It often causes mildew in storage, fruit rot, and deterioration of quality of flower bulbs. Penicillium suitable for the conditions of temperature 20 ~ 30 °C, relative humidity of 90% or more, like growing in an acidic environment.
(4) Prevention and control methods Pay attention to environmental sanitation, keep cleanliness around the cultivation room and cultivation, and timely dispose of waste. The inoculation room and mushroom house should be cleaned and disinfected according to regulations; the operator must ensure that the sterilization is thorough during the seed production, and the bagged strains should be handled with care in the handling process to prevent the rupture of the plastic bag; regular inspections have found that the strains are contaminated. Should be removed in a timely manner, and never sow species with pathogens. If Penicillium occurs on the culture material of the mushroom bed, it can be ventilated and dried in time, and the room temperature can be controlled at 20-22°C. After the bacteria are inhibited, the routine management can be resumed. Adjust pH, increase pH properly, add 1% to 3% quicklime or spray 2% lime water during seasoning to inhibit growth of germs. Pharmaceutics and spices, with a 0.1% thiophanate-methyl-containing dry material, the control effect is better. It is also necessary to pay attention to the ventilation of the mushroom house and the mushroom farm to avoid high temperature and high humidity. When the disease occurs locally, it can be rubbed with 5% to 10% of lime water or lime powder in the affected area. It can also be excavated first, and then Spray 3% to 5% of copper sulfate solution to kill the bacteria.
The food thickeners are the modified food starch, polysaccharide or certain vegetable gums. When a food thickener or a thickening agent is added to beverage, it absorbs the fluid and the fluid thickens. Breaking down the starch reverses the thickening action and almost all water in the beverage is available as free fluid for absorption by the body. If the thickening agent is a vegetable gum, it will continue to hold water even during digestion. Thus a vegetable based thickening agent may reduce fluid availability to the body. Commonly used thickening agents are pectin, lignin, algin, gums and agar-agar.

Control method of edible fungi Penicillium
Penicillium is also called green mold. Penicillium frequentans, P. lilacinum, P. viridicatum and Penicillium chrysogenum are common penicillium species in the production of edible fungi. (P. chrysogenum), P. verruculosum. Penicillium can invade and harm the oyster mushroom, mushrooms, mushrooms and other edible fungi during seed production and cultivation.
