What are little brown mushrooms, and how do they grow in my yard?
Little brown mushrooms, also known as LBMs, are a type of fungi that can be found growing in lawns and yards. They typically appear as small, brown caps on thin stems, ranging in size from a few millimeters to several centimeters in diameter. These mushrooms grow from underground networks of tiny, thread-like structures called mycelium, which break down organic matter in the soil and absorb nutrients. The mycelium can be present in the soil for years, waiting for the right conditions to produce mushrooms.
The growth of little brown mushrooms in your yard can be influenced by various factors, including soil moisture, temperature, and the presence of organic matter. For example, LBMs often appear after heavy rainfall or irrigation, as the increased moisture in the soil stimulates the mycelium to produce mushrooms. Similarly, the presence of decaying leaves, grass clippings, or other organic matter in the soil can provide a food source for the mycelium, leading to an increase in mushroom growth. By understanding the conditions that promote the growth of little brown mushrooms, you can take steps to control their appearance in your yard if desired.
