Winecaps are pretty fickle because you never know when they are going to fruit. Other mushrooms are more consistent. It is because of the random natural of winecaps that they are not widely cultivated commercially.
I have talked to people who say that it can take 1-2 years for a wood chip pile to colonize and begin fruiting mushrooms. I started the pile in October with the plan to have mushrooms ready for sale at the Westiside Farmers Market before the season ends in late September.
Well it looks like there is a chance of a harvest. I discovered this little (partly eaten) winecap mushroom in my wood chip pile.
I take this to mean that there can be more to come this season.
