woody, attached laterally, or centrally, sometimes as a bracket with a 

 smooth hymenium. Stereum hirsutum attacks oak trees in which the 

 wood becomes brownish at first and in longitudinal section, white or 

 yellow streaks are found, hence the common name white-piped, or 

 yellow-piped oak. In the cross-section, these streaks are white specks, 

 and another name, that of "fly wood," is apropos. Further decom- 

 position follows. The rot of woods, known as partridge wood, where 

 the timber becomes speckled with white, is due to Stereum frustulosum

(Fig. 85). The fruiting bodies are hard and crust-like, light brown to 

 grayish , in color. The smothering fungus of seedlings is Thelephora 

 terrestris and T.laciniatum. Soft leathery masses are found at the base 

 young trees of the hard maple. These are numerous, shelf-like fruit of 

 bodies, hemispheric in shape and in -mass may completely surround 

 and smother the small tree. Hymenochcete noxia attacks tropic plants, 

 such as cocoa, tea, bread fruit, camphor and the like.
