What am I ?
It appears that the latest visitor to the edible landscape garden is a Brown Shelf Fungus. It was found on one of the logs that has been used as a garden seat. Fungi are many-celled filamentous or singlecelled primitive plants. They lack chlorophyll and must live on decaying plants to get carbohydrates.
The Brown Fungus produces hydrogen peroxide to decompose the cellulose in the wood. Since the hydrogen peroxide (H2O2) is a small molecule, it can move rapidly through the wood. This will mean that the decomposition will not be just surrounding the area of the hyphae or filaments of the fungus. The log will eventually decay and become part of the surrounding soil.
