which may be the type of a new species to be known as C. 
plumosa. The sporophores possess a stout base but are very 
profusely and finely branched, very much more so than 
C. mucida (P.) Schroet., and have been chiefly found on rot- 
ting elm and basswood stumps or logs. Spores freshly 
matured and sown in pure water before drying germinated 
within two to six hours. 
The germination differs from that of any other genus of 
the Myxomycetes. Through a small perforation in the wall 
of the spore the protoplasm escapes slowly as a vermiform 
body which possesses tortuous motions and slight amoeboid 
movement of the surface. In the course of fifteen minutes 
to one hour this shortens and becomes amoebiform, the devel- 
oping pseudopodia being quite short and slender but longer 
than those on the vermiform body. Four rather clear spaces 
appear in the protoplasm which precede the simultaneous 
Parti-division of the mass into a four-lobed body. These 
then farther divide once forming an eight-lobed body; minute 
pseudopodia developing the meantime over the surface of all 
the lobes. A single long cilium is now developed from the 
end of each lobe and quite violent lashings follow accompa- 
med by the continued development of the pseudopodia. _ 
The individual lobes separate frequently in pairs which 
remain for a time in communication but eventually separate. 
Sometimes three to six may remain joined for several hours 
assuming various shapes, but always showing the individual 
lobes and the long cilium. These frequently simulate the 
that which I have observed. In the first place they were not 
able to germinate the spores until after they had passed a 
poe OF drying, and then only in a nutrient medium formed 
Y 4 solution of rotten pine wood in water. They were not 
Paige form issued directly, and division began by bi-parti-
