Observation 150536: Agaricus arvensis group

When: 2013-10-31

Collection location: Luzerne County Community College, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Looks like the one with grayish gills did not fully mature before drying out and cracking along the cap surface. Ate one and left the others outside in the rain. KOH applied after the caps became fairly waterlogged; oldish to begin with. So I figure this is why I didn’t get a stronger yellow reaction with KOH (pale yellowish).

Odor not strong, pleasant, almondy. Context in cut stipe darkening slightly to tannish.

Growing in landscaped area with woodchips and stones strwen along the surface; a few shrubs. Habitat seems to favor one of the types closer to A. rodmanii… which appears to A. bitorquis again.
