of the second sort’’ by fusing with the end cell. These same 
odblastema filaments then go on to other procarps of the second 
sort. Each of these ‘‘fertilized’’ auxiliary cells sends out only 
one or two rows of from two to four carpospores. Oltmanns (67) 
says only one simple two- to four-celled spore chain arises from each 
of these secondary fusions, and we thus have a very interesting 
parallel to the conditions in the ascogenous hyphae, where from 
each vegetative nuclear fusion a single ascus results with typically 
eight spores. 
Among the Cryptonemiales Schmitz notes interesting minor 
differences in the manner in which the auxiliary cells develop 
after the secondary fusion. In Dudresnaya (FG. 5, C, D), Poly- 
ides, Petrocelis, etc., after fusing with the distant auxiliary cell 
the odblastema filament becomes cut off from it and the sporog- 
enous cells arise from the part corresponding to the section of the 
odblastema cell. Schmitz saw no nuclear fusions here, and each 
cell seems to maintain its individuality in a large degree. In 
Calosiphonia the contents of the odblastema cell go over to the 
auxiliary cell. Here the outgrowths or gonimoblasts giving rise 
to the spores arise from the portion originally belonging to the 
auxiliary cell. In this second case Schmitz believes that the 
nucleus of the odblastema cell goes over to the auxiliary cell, 
but he could have seen no real movement. In Gloiosiphonia the 
entire cell contents of the odblastema cell except the plasma 
membrane pass over into the auxiliary cell. There is an intimate 
fusion of the cytoplasms, and in this case Schmitz believes that the 
two nuclei unite in what he calls the “second sexual process.” 
He describes the protoplasm of the odblastema cell as moving 
over and combining intimately with that of the auxiliary cell, 
leaving the other empty except for the plasma membrane, and 
in this case believes that a nuclear fusion actually occurs. Olt- 
manns denies that there are ever any nuclear fusions here, but he 
figures the odblastema cell as empty and holds that the protoplasm 
and nuclei pass to the auxiliary cell. 
Schmitz may be wrong; the next step, however, in the de- 
velopmental stages which he describes would be the fusion of the 
nuclei, and with a nuclear fusion under such conditions We 
should have a further point of resemblance to the young ascus-
