Fairy Ring Mushroom
Scientific Name: Marasmius oreades
Category: fungi
Brief Description
A small, pale brownish mushroom commonly found growing in rings or arcs in lawns and grassy areas.
Characteristics
Caps are convex to flat, sometimes with a faint umbo, light tan or buff fading as they dry. Gills are free or narrowly attached, whitish to cream, and relatively distant from one another. Stipes are tough, pliable, pale, and velvety.
Habitat
Grassy areas, lawns, pastures, and meadows, often forming distinct rings or arcs.
When to Find It
Spring through autumn, frequently appearing abundantly after heavy rain.
Conservation Status
N/A
Ecological Role
Acts as a saprotroph, breaking down dead organic matter in the soil and releasing nutrients back into the ecosystem.
Easily Confused With
Can be confused with toxic lawn mushrooms such as Clitocybe dealbata or Inocybe species. Marasmius oreades can be distinguished by its tough, pliable stem that does not snap easily, widely spaced pale gills, and pleasant almond-like aroma.
Observation Tips
Look for circles or curved lines of mushrooms in untended lawns or parks, especially a day or two after rainfall.
Interesting Facts
The mycelium of this fungus grows outward in expanding circles over many years, sometimes resulting in historical 'fairy rings' that folklore once associated with dancing elves or fairies.
