The hyphae are hyaline when young, becoming yellowish to dark brown in age. The species of Septobasidium may be separated into two groups which would probably be given generic rank, were it not for such transi- tional forms as S. cirratum. In the more primitive group, the fructifica- tion is a loose, arachnoid, flocculent crust, with either unlimited growth at the margin, or restricted growth, resulting in reticulate or sinuously divided fructifications, giving the appearance of foliose lichens.
