Photographer: Daniel McNair
Date Photographed: 10 Dec 2014
Locality: U.S.A., Washington, King County: Magnuson Park, Seattle.
Elevation: [not provided]
Coordinates: , 47.676709° N, 122.253381° W.
Comments: These floating-leaved aquatics were found within the Magnuson Park reconstructed wetland areas but not in adjacent Lake Washington. The hairs/trichomes on the upper leaf lobes appeared unicellular at 20x magnification. I did not find any sporocarps attached to the individuals I observed. Identification confirmed by Ben Ledgler.
