There are some up near the ruins and some on the way up to Cornelia's Cottage (Cordelia's Cottage?). It's the lot up on the hill in the far upper right of the map. On the way up, there's a little area with a bench. There are two "strange mushrooms" and one Nightly mushrooms, which I have not been able to harvest yet. There is another area, but I'll have to check my game tomorrow to tell you exactly where it is.
