distorted in a long spire. Sometimes it has been seen divided 
into two branches, nearly equal to each other. The spore in 
germinating empties itself of its plastic contents, contracts, and 
diminishes in size. The pseudospores of Acidium crassum, P., 
emit three long filaments, which describe spirals, imitating the 
twistings of the stem of a bean or bindweed. In Alicidium Viole, 
Schum, one filament is produced, which frequently rolls up its 
janterior extremity into a spire, but more often this same extremity 
rises in a large ovoid, irregular vesicle, which continues the axis 
of the filament, or makes with it a more or less decided angle. 
In whatever manner placed, this vesicle attracts to it all the 
orange protoplasm, and hardly does this become settled and 
complete before the vesicle becomes the starting point of a new 
development, for it begins to produce at its apex a filament, 
more slender than the previous one, stiff, and unbranched. 
According to M. Tulasne, the germination of the pseudospores 
of Keidium Euphorbie on Euphorbia sylvatica differ in some 
respects from the preceding. When dropped 
upon water these spores very soon emit a 
short tube, which ordinarily curves in an 
arch or circle, almost from its origin, attain- 
ing a length of from three to six times the 
diameter of the spore; then this tube gives 
rise to four spicules, each of which pro- 
duces a small obovate or reniform sporule ; 
the generation of these sporules absorbs all 
the plastic matter contained in the germ- 
tube, which permits of the observation that 
it was divided into four cells correspond- 
ing with the number of spicules. These

delicate, not extending more in length than three times that of 
the long axis of the sporule, often less, reproducing at its 
summit a new sporule, differing in form and size from that 
which preceded it. This sporule of the second formation be-
