"Alternatively, scientists have proposed that fairy circles are the result of plants arranging themselves to make the most of limited water resources in a harsh, arid environment."

I've always found Fairy Rings in the lawn, fascinating.

"Fairy rings are circular areas of abnormal turf growth that are most commonly found on lawns and golf courses where soils have high levels of organic matter, and in areas where trees have recently been removed. Due to their mysterious, circular appearance, fairy rings have been of interest since ancient times."

Not sure how, or if, there's any relation to this 'new' find in arid lands.

Not likely. ‘Shroom fairy rings are caused by an underground mycelium that originated at a point, and grows outward. When it produces the fruiting bodies...mushrooms...they’re at the margins of the mycellium. Still really cool, though.
