I watch for these each spring in our back woods, and saw our first ones pop up two or three days ago. This morning, suddenly, there was a plethora. Didjaknow, just like the Aspen, their colony shares a single root? Mayapple is also called mandrake. It flowers in May, but its “apple” comes later. The fruit may be eaten in small quantities but only after it turns yellow, and only after removing the seeds. Linnaeus described this plant in 1753. See more at wildfoods.ca.
The mayapple plants popped up over the last ten days or so, and today I noticed the first blooms. But you have to bend down a long way to get a photo.
See Wikipedia reference.
That was before breakfast April 16th. Here’s a bloom seen after supper May 6th:
We’ve had quite a lot of blooms on the mayapple plants this year. Maybe last year when I could only see one I just wasn’t looking early enough or carefully enough.
We have many mayapple plants now, but this is the only one we’ve seen with a flower so far. It’s on the path by our back fence, close to where I remember seeing a flower and subsequently a fruit photographed last year. Reference: Wikipedia
The Mayapple plants suddenly popped up about a week ago, in patches, here and there in the woods. This is the patch near the woodpile. Will keep an eye open for any flowers.
This is the fruit of one of the woodland plants seen in bloom Easter Saturday as below. Although it was trampled and left lying flat on the path by the dogs weeks ago, the fruit itself has remained green and possibly continues to grow. 
Thanks to Nick for providing the identification. I’m renaming this post from “unnamed fruit”. References: altnature.com,
