Yellow Mushroom in Moist Wood / jamur kuning

Fungi are one of the microorganisms that cause the color of wood to change and then cause decay if the quantity is excessive. Because mushrooms are not able to produce their own food, they depend on several natural materials including leather, cotton, rattan, paper and wood.

In terms of its relationship with wood, there are 4 main requirements before fungi can be on wood, namely: oxygen supply, air temperature between 5-38 °C, high humidity and of course the presence of wood. It is enough to overcome one of these conditions to prevent the wood on furniture or building construction from getting moldy.
It's pretty clear that we can't limit the presence of oxygen around wood because humans need it too. The air temperature needed by mushrooms to live is in the same range as humans and other living things. Even some types of mushrooms can live at temperatures below 0 °C. So in this section it is equally difficult to limit.

The most effective method is to keep the wood dry. That is why wood must be kiln dried at an MC level of 8-14% before being processed into furniture or other constructions (buildings or bridges).
Most fungi begin to live on wood that has an MC level above 20%. Below that level, it is very difficult for the fungus to start spreading.source
