ZODIOMYCES vorticellahius Thaxter. 
Tl 
ami normous individuals, some of them three millimeters in length, were obtained in the Paris Museum, 
\o. 121, on a large species of HydfOpkiluB from Rosario, Argentina. Despite the size of the receptacles 
in these individuals, the perithelia and other structures seem identical with the smaller forms, and certainly 
canned be separated specifically.

He pftack elongate, multicellular, terminated by a primary branched appendage, and consisting 
of a large and indefinite Dumber of superposed cells which distally become divided longitudinally to form 
successive tiers of cells which become proliferous on one side and give rise to a unilateral series of perithecia 
mil sterile (and antheridial ?) appendages. Perithecia having nine or ten wall-cells in each row and borne 
on two superposed cells which form a stalk. 
The material illustrating this very peculiar genus is for the most part in very poor condition, and 
includes but one mature individual. The appendages and young perithecia are so matted together that 
I have found it impossible to determine accurately the character of the antheridial branchlets. In a 
few cases flask-shaped cells have been observed which are borne one to three together on short branches. 
\\ In ther these are really antheridia, however, can only be determined by the examination of fresh material. 
The genus is most nearly allied to Zodiomyces and to Kainomyces , the short stout blunt and very 
peculiar j ithcciuin suggesting that of Kainomyces, while its two-celled stalk is similar to that of Zodi- 
tmyeet. The receptacle ends in a primary appendage which bears a number of filamentous branches, 
and below its base the perithecigerous area extends downward on one side for a variable distance. Whether 
this perithecigerous region originates endogenously, as in Zodiomyces, I have been unable to determine 
from the material available; but such does not appear to be the case. The elements arising from this 
region, however, consist of sterile rarely branched filamentous appendages which form a double row en- 
ring the other structures within, somewhat in the same manner that the circular series in Zodiomyces 
encloses the region from which the perithecia and antheridial appendages arise. The strobil-like perithe- 
lium is quite unique and no lip-cells appear to be differentiated. In some specimens the receptacle is 
very slender while in others it may be stout and densely cellular. 
The species does not appear to occur in America, but seems to be not uncommon in England where
