Thanks everyone! I will try to get some more pictures this weekend as Dominik suggests, so we can reach a definitive conclusion. Sadly, the microscopic picture is beyond my primitive capabilities, so no bonus points for me. And actually, not sure what is meant by "spore print"?
“All good things are wild, and free.” Henry David Thoreau
A spore print is where you lay the mushroom gills down on a piece of paper to determine the color of the spores. However myself I prefer to only eat mushrooms that I know we'll enough to not require a spore print. They don't really look anything like oyster mushrooms nor are they growing on a tree like an oyster would.
