What to Do About Excessive Vegetative Growth of Straw Mushroom Mycelium? Detailed Control Methods
During the mycelial growth stage of straw mushroom, a large amount of white fluffy aerial mycelium forms on the surface of the substrate, sometimes even growing into a white layer of mycelial mat, which delays fruiting and leads to low yields; the cause is excessively high temperature inside the compost heap. Control methods: after inoculating straw mushroom, regularly uncover the plastic film to ventilate and lower both temperature and humidity, and do not cover with too thick a layer of straw, so as to encourage the mycelium to grow into the substrate.

How to prevent and control excessive browning of shiitake mushroom logs that results in no fruiting
1. Causes of the problem. Log browning is a physiological process in the development of shiitake mushroom mycelium and is also a sign of physiological maturity of the mycelium. Suitable conditions for log browning: temperature of 18°C to 24°C, air humidity of 80% to 85%, some scattered light, and good ventilation. If the indoor temperature exceeds 25°C during browning and this high temperature lasts for a long time, it can cause the logs to secrete large amounts of yellow water and pigments, thereby forming a thick brown mycelial skin. The thick mycelial skin formed can block air, causing the mycelium to receive no oxygen and be unable to
