Is the underside of the Tricholoma mushroom cap and its interior turning black toxic, and can it still be eaten normally?
Tricholoma mushroom is also called white mushroom because it is white all over, and it is also a rare edible fungus with high nutritional value. But why do some Tricholoma mushrooms bought and left for a while turn black? Is the underside of the Tricholoma cap turning black toxic? Is the inside of the Tricholoma

Common abnormal phenomena and handling measures in oyster mushroom cultivation in late spring and early summer
Late spring and early summer is a good season for cultivating oyster mushrooms. However, due to improper operations, some mushroom growers experience abnormal phenomena such as yellowing and necrosis of mushroom logs after fruiting, souring and stinking of the substrate, and delayed fruiting after the mycelium has fully colonized the bags, which reduces the success rate, yield, and quality and directly affects economic returns. Based on many years of production practice and the experience of growers, the author summarizes the causes of these abnormal phenomena and the handling measures as follows. 1. Mass death of young mushrooms after fruiting from the mushroom bags In late spring and early summer, sometimes after the mushroom logs fruit, young mushrooms turn yellow and soft in large numbers, their bases thicken, and then they wither and rot into dead mushrooms.

What are the reasons why oyster mushrooms do not fruit or fruit abnormally?
During oyster mushroom cultivation, it is fairly common for a fully colonized, mature mushroom bed to delay fruiting, or for a bed that has already produced 1 to 2 flushes to stop fruiting normally. The reasons include the following: 1. Substrate temperature too high. In a mushroom bed with mature mycelium, if there is no influence of lower temperatures, the substrate temperature drops very slowly. If the substrate temperature is above the fruiting temperature range, primordia are not easily formed; this phenomenon is most common in low-temperature strains planted in autumn. 2. Unsuitable environment. The ambient temperature where the mushroom bed is located is higher than the fruiting temperature range of the planted strain,

What to Do When Straw Mushroom Growth Is Abnormal? Detailed Explanation of Prevention and Control Measures
Straw mushrooms (Volvariella volvacea) are a high-temperature type of edible fungus and are the edible fungus variety with the largest cultivation area in summer locally. During the production of straw mushrooms, it is common to see patches of young mushrooms wither and die. Analysis shows that there are many causes of young mushroom death, mainly the following aspects. (1) The compost is too acidic. (2) The compost temperature is too low or the temperature changes abruptly. Straw mushrooms are...
