What Are Fairy Ring Mushrooms?
Marasmius oreades – these rather charming, unassuming little fungi are very common in lawns and other grassed areas such as parks and playing fields. – They typically grow in circular rings – starting as a single clump and widening a little each year as the underground mycelia spread out in search of new resources. The place where they grow can often be identified even in the complete absence of the fungal fruiting bodies, by a ring of darker, taller, thicker-growing grass. It’s not uncommon for these ring formations to become interrupted or irregular in shape due to a wide range of environmental factors.
