Observation 111237: Entoloma abortivum (Berk. and M.A. Curtis) Donk
When: 2012-09-23
No herbarium specimen
0 Sequences

The aborted forms resemble mushrooms that have been attacked by a hypomyces. Looks like an armillaria fruiting was well under way when this batch of E. abortivum showed up. Note the reddish staining on the aborted stipes.

It looks to me like E. abortivum has completely wiped out the armillaria that would have otherwise fruited on beech wood (along the Falls Trail at Rickett’s Glen). No armillaria mushrooms found on beech, but there are some nice fruitings on oak.

Do you see the resemblance of this large Entoloma mushroom to that big one you had in your gagrage?… the one with the wierd dark zone along the outer cap margin?

Look at the photo of the aborted forms. One can see the stems of the Armillaria mushrooms that have been attacked.

Looks like a nice fresh find Dave. Al Tondora would love to have them.
