Here's a very typical looking white corticioid fungus. It could be just about anything, but we believe it is Hyphoderma puberum (hi-fo-DERMA-uh PUBE-er-um). Hyphoderma means hyphal skin and puberum refers to the large cystidia that make the surface of the fruiting body look pubescent under a hand lens. Many of the fungi you find when turning over logs are this nondescript color. However when you look at them in the microscope they are nothing alike. Some have really huge or strangely ornamented spores, some have bizarre crystals, and some have spectacular cystidia. most of them are worth a good look or two. One of these nondescript white corticioid fungi, Phanerochaete chrysosporium has the potential for use in biopulping and bioremediation. Take the link to learn more about this fungus.
