Brown to black sclerotial structures, a few millimeters in diam- eter, consisting of coarse, broad, short-celled hyphae of peculiar and characteristic branching also occur freely, both in nature and in culture. Fig. 293. These cells seem capable of functioning as chlamydospores. The hymenophore consists of a dark network of hyphae which changes to grayish-white when spormg. It frequently entirely surrounds the green stems of the host near the groimd. The tips of the outermost hyphae are sterigmatate. The spores germinate readily, developing into typical Rhizoctonia myceliiun. The relation which the various Rhizoctonias which have been described on numerous hosts may bear to the one species under.
