Sclerotes were formerly classed to- gether under the generic name of Sclerotium before it was recognised that such bodies are mere growth forms, or rather resting forms, of myceles of different fungi. Such a strand-mycele as that of Agaricus melleus (L.), formerly considered an independent fungus (Rhizomorpha), noticed above, has been aptly called a sclerote with a growing-point. B. Frank (Ber. Deutsch. Bot. Gesellsch., 1885) has described masses of fungal hyphae having a dense sclerotioid structure inves

In nutritive solutions conidia are formed in large numbers, and multiply yeast-like till nutriment fails. Ust. succisae Magn.^ frequents the anthers of Scabiosa Succisa, and forms pure white spores, easily distinguished from those of the two preceding species. The anthers appear to be thickly covered with glassy granules

RMRCDPED–. Diseases of economic plants. Plant diseases. Cereals 317 occurring in the fields in spots. They are known in many countries on wheat, oats, barley, rye, and rice, and are very destructive in Europe and Australia. The diseases in their va- rious forms have many names, among them Take-all, White- heads, Pietin. Any one of several fungi may cause foot-rot, especially when the wheat plant is weakened by adverse en- vironmental conditions. A foot-rot of wheat due to unknown cause was reported in Oregon in 1902, and one due to Hel- minthosporium in Illinois and Indiana in 1919. Burning of the stub
