100 Species Challenge #42

Specimen #42 Black Knot Fungus

Apiosporina morbosa

Occurs on plum and cherry trees. Native to North America. You might be able to see the horizontal lenticels (breathing holes. See _Discover Nature in Winter_.) on the branch in the upper right.

I have not read anything that says this organism has a use for humans. We see this fungus fairly often in all of our walks all over the state. It is hard and looks black and dry. The form is irregular.
