Abundant in grassy, landscaped soil, faintly phenolic, some slight, slow yellowing. Decidedly unlike the xanthodermoid species which hasreplaced almost all the edible urban Agaricus which used to inhabit Oregon lawns and gardens.

first off, is the photo oversaturated or overwarm at all?
Microscopy is not terribly helpful with Agaricus.
Did you scratch the stipe base?

Rick Kerrigan is supposedly going to introduce a number of new large, dark-capped Xanthodermati, and I’m not familiar enough with the soon-to-be species or variation therein to know what you could to to clinch this one as of this moment.

The habitat is my main concern for A. hondensis – usually more a mushroom of forest duff.

A. hondensis, but these are darker and a bit more coarsely scaled than is typical.
