Status

Found scattered or in clusters on ground near rotting wood in mixed woods (J. Solem, pers. comm.). "Aborted fruiting bodies actually result from the growth of Armillaria (honey mushroom) attacking the fruiting bodies of the Entoloma. However, some recent studies now suggest that it is the Entoloma which attacks the fruiting bodies of the honey mushroom. Nevertheless, In all my years of finding this mushroom, I have never observed the honey mushroom fruiting among the aborted bodies. Sam Ristich, my mycological guru, was able to grow-out both myceliums from a single aborted body on agar plates." (L. Biechele, pers. comm.)

Description

Cap: Pale gray/gray-brown, convex with low umbo, inrolled edge. Gills: grayish (pinkish in age), close, subdecurrent. Stalk: Whitish/gray, base usually enlarged and coated with white mycelium. Aborted fruiting bodies: White with pink streaks, usually in clusters; flesh spongy. (J. Solem, pers. comm.)

Entoloma abortivum, commonly known as the aborted entoloma[2] or shrimp of the woods, is an edible mushroom in the Entolomataceae family of fungi. In Mexico they are called “Totlcoxcatl”, meaning “turkey wattle”, due to its irregular shape.[3] Caution should be used in identifying the species before eating[4] (similar species such as Entoloma sinuatum being poisonous).[5] 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.[6]

It was believed that the honey mushroom, Armillaria mellea, was parasitizing the entoloma. But research[7] 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.[citation needed]
