I was out for 6 hours in Lincoln and Madison Counties yesterday with nothing to show for it. I managed to collect some fiddlehead ferns, but I did not see other signs of adequate moisture like dutchmens breeches and may apples up and setting flowers that I usually associate with morels popping. Hopefully We can get some good moisture over the next week and a half and things will actually kick off. As for cooler temperatures I would not worry about them effecting future mushrooms, I am more concerned that we might have an off year if we get too many more of these 80 degree days with no measurable precip. which could really limit morel yeilds outside of wet creek bottoms. Good luck hunting, dont think they are out there in force yet, but keep looking.
