Observation 2873: Psathyrella bipellis (Quél.) A.H. Sm.

When: 2007-03-18

Collection location: Howarth Park, Santa Rosa, California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available


These were found in a large troop under an unknown tree (a cultivar, I think), but there’s a coast live oak very nearby, at the edge of a parking lot. There’s lots of debris but no wood chips that I could see and it’s not a grassy area. The young, fully developed specimens are about 2.5 cm wide with a stalk about 5cm long and 4 mm wide. Conditions were very dry when these were found so I don’t know if they were ever viscid.

  • Spore print is either dark purple brown or black.

  • There are minute veil remnants on younger specimens as well as the obvious veil on the button. Some have annuli on stipe.

  • Gills are pale tan on younger specimens and mauve brown on older ones. Some are unevenly colored (although I wouldn’t call it mottled) more so as they age, and adnexed.

  • Stalk is hollow.

  • Pileus and gills have a sturdy, solid feel.
