Observation 2196: Fomitopsis cajanderi (P. Karst.) Kotl. & Pouzar
When: 2007-01-27
No herbarium specimen

Notes: Nice pink color of these polypores.

The talk on Saturday of this foray was by Dr. Terry Hinkel of Humboldt State University, and it was about wood rotting fungus, most of which seem to be polypores. Anyway, there are different types of wood rotters, eating away at different parts of the wood. These are heart wood rotters, which go after the cellulose in the interior dead wood at the heart of the tree. Once the cellolose is gone, only the brown lignin is left, which loses all strength, and becomes crumbly. But also with heart wood rotters, there are top rotters, and but rotters. The top rotters go after the heart wodd from the top of the tree, and the but rotters go after it from the base. These are top rotters, and the fruitings of these are only at the tops of trees. But as they rot out the center of the tree, it weakens, and eventually breaks off in the wind. Then you get to find infected branches lying on the forst floor, and the fruiting bodies.
