Zusammenfassung: | 1. It might be better to treat this material as a new variety of O. concatenatum, so far as the dimensions of the oogonium and oospore and the diameter of the vegetative and suffultory cells are concerned, because there is not enough difference in dimensions to establish a new species. We cannot overlook, however, the difference existing in the length of the vegetative cells and of the suffultory cells in both species. 2. The marking of the median spore coat of the oospore of O. nebraskensis is different from that of O. concatenatum f. Hutchinsioe in being "punctate," while the latter is "scrobiculate." 3. The most distinguishing character of this species is the position of the pore in the oogonium, in the supramedian position instead of the superior. |
