owing to the fact that I have been unable to obtain its host in any considerable numbers. It l« L n 
collected in one instance on StintUS UmgWMuluB Jit Kitten' Point, M< 00 one of inanv s]>ecim< us of il» 
host examined. As I have previously pointed out, it may prow only a very curious development of 
Compsomyces, to which it is at least very closely allied. As in the case of the genus last mentioned i 
has seemed best to regard the basal stalk-cells of the peri thecis I branch* from the rc< \Uu-\v 9 fiDtn 
which the perithecia originate as well as the peculiar sterile branches which subtend it, raih< i tlian as 
parts of a compound perithecial stalk-cell.

thus far described. It is clearly distinguished by its simple axis of suj>erposed cells one or inon of w hich

Receptacle consisting of a single series of BUperposed cells, becoming variable in number as a r ill 
of intercalary division; hearing distally a single perithechim and an antheridial apjioidage. Th<- |- 
pendage consisting of a series of superposed cells, several of which, above its ba^al «»r staUWIl, 1 r 
simple antheridia, which are cut off distally on one or both aid , by oblique septa. 
This genus, although it lacks any very striking diaracteristie, ia one of the rare instanc. in the faimly 
in which the primary receptacle becomes multicellular through inter, hoy divis'u of its cells. I In

theridia distally by an oblique septum, while later they develop a variable number of filan tou bran<l„ -. 
The genus appears to bear some resemblance to Compmyce* in the character of its penth< iu id 
antheridia, and also to Ilydwphilomyrcs and Misgomyxi in the presence of intercalary growth, and a 
i he general relations of its parts.
