Central Pennsylvania Wild Mushroom Club

  This one has been giving Bill and I a tough time. Neither of us has seen it before. Definitly an Agaricus. Fits the description in Phillips. No bruising, nonreactive with KOH. There's hundred's of these up here. At first we thought it was an import of cremini from mushroom soil. Have not sampled it but Boy was I tempted!  Any thought or insights? Have any of you found this one? I did some spore prints so we might attempt to cultivate this one over the winter. I can't find much information on it in the USA. Some say edible- some say avoid. It's definity not andrewii.                                            Bill did the microscopic on this one. He needs a better addition to his microscope to do the measurements of the spores. I forget what that thing is called. It's a comparison scale or something like it. If any of you can provide that let us know. It would be much appreciated!
