I first spotted this fungus, I believe, in the spring. I noticed that the fungi looked like yellow lentils on the ground. Then, over the summer, I spotted brown cups on some of the bark chips and Jenny reminded me of those lentil-looking fungi...of course! This fall, on closer inspection, I saw little seeds or spores in the cups. Then, I happened to find a vintage book I had been pining for at Powell's during a quick weekend get-away.
There it is, Common Bird's Nest. If you're observant, you'll notice that the subtitle of the book is dated, but still, the book is a gem. On a wee bit of further research, I learned that there are five species of Bird's Nest Fungus and I'm not totally sure yet if the one I found is still called Common Bird's Nest. Those "eggs" it notes are peridioles that contain the spores.
I'm starting to achieve my goal of "mushroom" hunting for the fall.
