On the way to the park, we found two prized medicinal mushrooms: reishi and hen-of-the-woods. Growing right along the side of the road on the base of an oak tree in the neighborhood.
With the park we found good examples of most of the broad classifications of mushrooms you'll see: gilled cap-and-stalk mushrooms, boletes (cap-and-stalk mushrooms with pores instead of gills), shelf or polypore mushrooms, and even some coral mushrooms. We saw some fantastic examples of how mushrooms spread their mycelium through the vertical tube structure of wood. And we looked at the colored spores they drop to reproduce.
At one point someone said to me, "You can walk through the woods and it's just beautiful, but there are so many things to see if you stop and look!" Indeed.
