In figure 9 (PL XXIX) is shown the typical method of germi¬ 
nation. Each cell produces one or more hyphae, each cell of 
which will have a single nucleus. Very rarely has a cell been 
found, in any of the cultures, which has two nuclei. If, on the 
other hand, a study is made of sections of very young fruiting 
bodies as found in nature, it is soon observable that a great 
number of anastomoses take place, and the greater number of 
cells are typically binucleated. It is to be noted, however, that 
many of the cells found in the neighborhood of the spore from 
which the fruiting body developed, and which may occasionally 
be found in sections, are uninucleated, and that at a short distance 
from the spore they are found to contain two nuclei. There is 
no question but that many of these binucleated cells have arisen 
as a result of the fusion of adjacent hyphal cells, but many direct 
descendants of uninucleate cells are also found to contain two 
nuclei.

one nucleus. 
It has not been found possible, as a result of these studies on 
Dacrymyces, to discover anything quite comparable to the pri¬ 
mary and secondary mycelia described by Falck (9, 10) and 
Bensaude (3, 4), and at no time have clamp connections been 
observed in these forms. The hyphae from different parts of an 
individual fruiting body vary greatly in diameter, and very 
often the cells which develop into basidia are much smaller in 
diameter than adjacent cells. Figures 10 and 11 show two bas¬ 
idia which are derived from such hyphae. The cells immediately
