Appearance
First named "Clitopilus abortivus" by Miles Joseph Berkeley and Moses Ashley Curtis, it was given its current name by the Dutch mycologist Marinus Anton Donk in 1949.It was believed that the honey mushroom, "Armillaria mellea", was parasitizing the entoloma. But research has indicated that the inverse may be true - the entoloma may be parasitizing the honey mushroom.
There is still some disagreement by mushroom collectors about this since it is common to see both the aborted and unaborted forms of the entoloma on wood and in leaf litter, whereas Armillaria generally only fruits on wood. Both versions of the entoloma have also been observed when there are no Armillaria fruiting.
Both the aborted and unaborted forms of the entoloma are edible.
