*Hygrocybe* subsect. *Hygrocybe*	Pgrunow	29% (1)
Recognized by sight: blackening wax caps, similar to Singeri sensu CA, but with unusual odor
*Hygrocybe nigrescens* sensu Largent	Pgrunow	57% (1)
Recognized by sight: large and smooth completely-blackening hygrocybes in large umbo or rounder. Stipe always dry and even slightly silky before blackening. Apex and base yellow. Caps perhaps viscid near pileus ctr at first, but then dry out and are smooth. Before blackening, gills were whitish or yellow and caps were yellow-orange or deep red. They occasionally exude yellow droplets when cut. Context is white. I don’t remember detecting this odor with H. “singeri” before and it was present even in younger specimens. More of the same were later found growing with oaks. Used references: Mushrooms of the Redwood Coast, Mykoweb, Mushroom Observer observations/comments
