title: TWO NEW SPECIES OF OEDOCLADIUM(1).
abstract: Two new gynandrosporous species of Oedocladium from the United States were isolated into unialgal culture and comparative studies were made. The new taxa described, O. carolinianum sp. nov. and O. cir-ratum sp. nov., are morphologically very similar. Both species have an opercufate oogonium with inferior division, oospore walls with the middle layer ungulate, and hyaline suffultory cells containing a small amount of vacuolated cytoplasm. Conditions for sexuality in culture zuere determined for both species. Zoospores and akinetes serve as means for asexual reproduction.
