Circle of tall grass - also called "Witch's Round" - formed by a fungus whose mycelium grows in annular extension, such as the St. George's Tricholoma (Calocybe gambosa) for example, in the grass of a small meadow left fallow near a rapeseed field, in spring, in May, in Picardie - France.

The grass grows higher on the circle formed by the mycelium of the fungus that spreads in the soil and fertilizes it by producing nitrates. Several species of fungi produce annular mycelium, especially Tricholomas, Clitocybes, Hygrophores, and Lepiotes.
