Comments: 

Knowing a little about the life cycle of this fungus makes it even more interesting than the orange tentacles of goo. The life cycle starts out as mycelium that is hibernating in a cedar tree. Once the spring comes, it will form an orange gelatinous substance on the branches and the ends of the branches, often forming long tentacles. Once this goo dries, it releases millions of spores into the air. The next stage of the life cycle can only be completed on a separate species of tree in the Rosaceae family. This includes Crabapple, Hawthorne, and Serviceberry. It will form cankers on the tree and growths on the fruits of the trees it infects.

Overall, it is a cool fungus with a great story.
