Marasmius cohaerens is a species of gilled mushroom which is fairly common in European woods.

It also occurs though rarely in North America, and there other varieties have been identified (the European one being M. cohaerens var.

[1] This species was originally described by the mycologist Christiaan Hendrik Persoon in 1801 as Agaricus cohaerens.

[5] Then in 1878 in a common work published in London, Mordecai Cubitt Cooke and Lucien Quélet assigned the current name which has remained the same for over 100 years.

[5] The Latin epithet cohaerens has the same origin as the English word "coherent" and means "keeping together" (i.e. it is difficult to pull the mushroom apart).
