This might be characteristic of the domain you have been foraying. I was able to find them this year at bout the same elevation line where the water content in the soil, the temperature been hovering in mid 50 oF at night and up into low 60 oF during the days over a period of 13 days and where the plants from ferns, Showy Orchid to Mayapples were thriving under a canopy of really old Tulip Poplars. I would say do venture into an unknown area and you might be surprised. You might want to look for Dryad Saddle which you might find shelving on a dead Elm Log…it is creamy looking with brown scales on top of it. It does smell like stale olive oil, but taste great when picked young. I will be posting some pictures ...Do your Google on it to get good. Happy hunting.
