The hymenium is smooth, or pimply, and consists of club-shaped basidia with four basidiospores. The species are mostlyfound on wood. C. vagnm-solani in its sterile form is known as Rhiz-odonia, which apparently has been found on sugar beet, bean, carrot,cabbage, potato, egg plant and a number of other hosts. The hymeno-phore of this species is white with short basidia and elliptic frequently entirely surrounds the green stems of its host near theground. The persistent hymenophore of Stereum is leathery, or 222 MYCOLOGY woody, attached laterally, or centrally, sometimes as a bracket with asmooth hymenium. Stcreuni kirsiitum attacks oak trees in which thewood becomes brownish at first and in longitudinal section, white oryellow streaks are found, hence the common name white-piped, oryellow-p
