If you see what looks like white paint splashed on dead wood, chances are you're seeing the fungus Irpex lacteus. While many of the fungi profiled in this series have been host-specific, Irpex can infect almost any kind of wood. It's the only fungus I have found growing on the hardy weedlike Tree of Heaven (Ailanthus altissima), and can even grow on bamboo. In one exceptional and bizarre case it infected a human being.
This fungus is one of a few species sometimes called "crust" or "parchment" fungi. The fruiting body emerges from the wood as a thin spreading layer on the underside of the wood, or the side. A small lip or shelf forms over the crust when it forms on a vertical piece of wood, to protect the spore-producing surface from rain. The spores are produced from a texture resembling hundreds of tiny teeth. The crust generally grows in fall, but persists year-round.
( Several examples )
