Observation 174478: Entoloma abortivum (Berk. and M.A. Curtis) Donk

When: 2014-08-18

Collection location: Westwood Cemetery, Oberlin, Ohio, USA [Click for map]

Who: peterichards

No specimen available

Found in managed grassland with mature trees, under an old beech under which tree I have previously found E. abortivum including good non-parasitic fruiting bodies, usually later in the fall. The current observation occurs at the same time that we are having an explosion of A. tabescens all around town. A. mellea should not be showing up until later around here, and not in this ground-level context, so it is unlikely to be the host.

An advanced search of this site did not turn up any photo-documented examples of E. abortivum in immediate association with A. tabescens, though one other Ohio observation has text saying that A. tabescens was involved. So hopefully this is a useful observation about who is parasitizing whom!

Within 10 feet of these images were a totally normal cluster of A. tabescens and a white lump with no recognizable mushroom caps present.

Entoloma abortivum parasitizes several Armillaria species including A. tabescens.
