What Makes Oyster Mushrooms Turn Yellow?
Imagine you’re wearing a coat that’s either too warm or not warm enough – you’d feel pretty uncomfortable, right? Well, oyster mushrooms can feel the same way about the air around them. If the air is too wet or too dry, or if it’s moving around too much or not enough, the mushrooms can start to turn light brown. It’s their way of saying, “Hey, I’m not happy with this weather!”
- Room too humid or too dry:
Just like our skin can get dry or sweaty, mushrooms also react to the moisture in the air. Oyster mushrooms can go bad from lack of moisture. They need balanced environment to stay healthy and white. Too much air or too much humidtiy make them soggy and dry out.
- Not enough fresh air:
Oyster mushrooms need to breathe! If they don’t get enough fresh air, they can’t get rid of the carbon dioxide they produce. This can stress them out and cause decolorization.
- Wind blowing directly on them:
Imagine a strong wind constantly hitting you – it would be bothersome, right? Mushrooms feel that pressure too, and it can make them turn a yellowish color.
- Big changes in how wet or dry air is:
If the air’s moisture level keeps changing, it’s like the mushrooms are trying to adapt to different weather every day. This can be too much for them, and they might start to change color.
Sometimes, Little yellow spots can show up on the mushroom caps. This can happen if the ground they’re growing on isn’t very good, or if they get sick from a fungus green mold (trichoderma) or bacteria, or if water sits on them for too long when it’s really humid.
- Not-so-great growing ground (substrate):
Oyster mushrooms need a good, nutritious base to grow on. Oyster mushrooms can turn yellow If the substrate isn’t right, it can affect their health and color.
- Getting sick from other tiny living things:
Just like people, mushrooms can also get sick. If they’re attacked by harmful fungi or bacteria, it can cause them to turn yellow or gray color.
- Water hanging out on the mushrooms in a humid room:
When it’s really damp, water can collect on the mushrooms. If it stays there, it can make them look yellow and feel unhappy.
So, keeping oyster mushrooms happy means watching the air around them, making sure they have a comfy home to grow, and protecting them from illness. By doing this, you’ll help them stay a healthy white color!
How to Fix Yellow Oyster Mushrooms
Just like you visit a doctor when you’re under the weather, your mushrooms need your attention when they start to change color.
Playing detective with your mushrooms is key; you can’t make wild guesses about their health. To start, you might need a hygrometer – that’s a tool that measures humidity, or how much water is in the air.
Now, if your oyster mushrooms have developed light gray or brown color and seem to be wearing a little crusty coat, it’s a sign that the air might be too humid.
On the other hand, skin of the mushroom getting yellowish and edges of the mushroom appear cracked, and the stems have turned brown, this could mean the air is too dry. These are clues that tell you about the air’s wetness around your mushrooms.
But what if the humidity feels perfect and you still see slight yellowing spots? This could be a hint that the air isn’t moving enough.
Mushrooms need fresh air to stay healthy. Cracks on the mushrooms might also suggest that the air flow is too strong. Think of mushrooms as preferring a light caress rather than a strong gust of wind.
Remember! Consistency is key for mushroom happiness. The air’s humidity where your mushrooms live should be steady, within the sweet spot of 80-95 %. If the humidity jumps around too much, it can stress out your mushrooms, causing them to turn yellow, become dry, and crack.
And what about if you suspect your mushrooms are sick? It’s time to be a bit of a scientist and inspect a mushroom closely for germs.
The soil or substance they grow on might also be a culprit, harboring unwanted germs. You’ll want to check both. Discovering any tiny pests means you’ll have to use special, safe sprays for both the mushrooms and their growing medium to protect them from harm.
Other Troubles for Oyster Mushrooms
Oyster mushrooms are usually a delight for gardeners, but sometimes they can run into health problems, showing up as a change in color. Knowing the different issues that can cause this discoloration is key to keeping your mushroom crop thriving and healthy.
What is Bacteriosis?
Bacteriosis might sound complicated, but it’s essentially an illness that can cause oyster mushrooms to turn yellow. Although it’s not very common, certain conditions like high humidity and warm temperatures can encourage its spread. Typical symptoms include:
- Yellow spot that are wet and slimy to the touch.
- Spots that seem to blur into the surrounding area.
- A mushy feel when you press on the mushroom.
- Mushrooms that have started emanating ammonia-like odor instead of earthy smell.
While these signs can hint at bacteriosis, caused by the Pseudomonas tolaasii bacteria, only a scientific test can confirm its presence.
It’s important to note that not all spots are a sign of this illness. For example, spots with sharp edges or those that appear to be simply water-soaked may indicate other issues.
Addressing the issue involves more than treating the mushrooms; you often need to remove the infected ones completely.
To prevent future outbreaks, adding calcium chloride to the soil can create a less hospitable environment for the bacteria.
Could It Be Parasites?
Many mushroom growers consider that dark spots or blemishes in mushrooms can be infestation of tiny insects such as gnats or midges.
These insects are small and difficult to detect, but they can cause significant harm to your mushrooms. Here’s what you might notice:
The presence of minuscule tunnels in the mushroom substrate or spotting the larvae, which resemble tiny worms, is a clear indication that these insects have made your mushroom bed their home. Additionally, rust-like spots can suggest larvae activity.
To combat these invaders, you’ll need to take a two-pronged approach. First, use insecticides in the area where your mushrooms grow to eliminate adult pests. Then, treat the soil with insecticidal substances to target the larvae.
Watch out! Insects can build resistance if you repeatedly use the same insecticide. To avoid this, alternate between different types of insecticides to keep these pests at bay effectively.
By staying vigilant and understanding the signs of these common issues, you can take swift action to protect your fresh oyster mushrooms from yellowing and other health problems, ensuring a bountiful and healthy harvest.
Keeping Oyster Mushrooms Happy and Healthy

Before you use any chemicals, make sure you’re dressed for the job with an apron, boots, gloves, glasses, a hat, and a mask. And don’t forget to steam and clean the ground the mushrooms grow on to keep it germ-free.
To keep bugs away, you can spray insecticides in the room. And to stop bug babies from hatching, you can mix things into the ground that stop them from growing their hard outer shell.
