17 Types of Lawn Mushrooms (with Pictures) – Identification Guide
Mushrooms growing in lawns are a common sight. Small clusters of white, brown, orange or even red fungi can appear in grass seemingly from nowhere. Most types of lawn mushrooms have a characteristic umbrella-shaped or flat cap on top of a slender stem. Even though many mushroom species prefer shaded areas, lawn mushrooms have the habit of popping up even in sunny yards.
Many varieties of common garden mushrooms are white with domed caps, have brown or white gills, and grow in small groups among grass blades. For example, false parasol mushrooms (Chlorophyllum molybdites), field mushrooms (Agaricus campestris), puffball mushrooms, and white dunce caps (Conocybe apala) are all types of common garden mushrooms.
However, several varieties of mushrooms that grow on lawns are orange, tan, or brown. For example, fairy ring mushrooms, weeping widow mushrooms (Lacrymaria velutina), Agaricus placomyces, and scruffy twiglets (Tubaria furfuracea) are colorful lawn mushrooms.
Correctly identifying species of mushrooms in your yard is vital. This article is only a rough guide to help recognize common garden mushrooms. It is not meant to be a definitive guide for identifying poisonous lawn mushrooms or give advice on picking mushrooms in your garden.
Some types of mushrooms in gardens are highly poisonous and can cause severe health consequences. Therefore, never eat any type of mushroom from your garden without identifying the species with 100 percent certainty.
In this article, you will find helpful tips and guidelines about lawn mushroom identification. In addition to descriptions, pictures of common garden mushrooms will help you spot the type of fungi growing in your lawn.
How to Identify Lawn Mushrooms
The identifying features of common lawn mushrooms are the color, cap shape, length of the stem, the color of gills under the cap, and aroma. Some mushrooms in the yard have a spongy feel, whereas others have gills or pores under the cap. Slicing the mushroom also reveals the color of the flesh.
Why Mushrooms Grow in Lawns
Mushrooms growing in your lawn are a sign your lawn and soil have plenty of organic matter. Lawn mushrooms are fruiting bodies that feed on decaying organic material. Fungi grow in lawns when conditions are ideal. This is when there is usually plenty of rainfall, high humidity, warm weather, and shaded conditions.
Some varieties of lawn mushrooms appear in late summer or early fall in your yard after it’s been raining. These white spongy growths contrast with lush green grass, making them easy to spot. The appearance of yard mushrooms is a sign they are decomposing organic matter in the soil, boosting the nutrient content of your turfgrass.
Mushrooms also grow in lawns if there are old tree stumps under the surface. For example, you may see fairy ring mushrooms growing in a circle in the middle of a lawn. These orange-brown mushrooms grow from decaying wood below the surface.
What should you do about mushrooms growing in your lawn? In most cases, you can leave them or run the lawn mower over them. However, if you are concerned about poisonous lawn mushrooms, you could remove them and put them in the compost heap.
