THAXTER. — NEW LABOULBENIACE^E. 449 



almost horizontal, terminating near the base of the beak-like pointed 

 apex, which projects somewhat obliquely from the right side : the 

 external row of wall cells producing above the fourth cell a large append- 

 age, geniculate at its base, tapering distally where it curves outward, 

 consisting of from ten to twenty cells, the terminal cell rarely bearing 

 one or more slender brauches. Receptacle consisting of three superposed 

 cells, the basal one usually opaque, except distally, and continuous with 

 the foot, surmounted by two cells from which arise the periiheciuin and 

 the appendage. The appendage (usually broken) curved outward and 

 upward, consisting of about ten superposed cells, the upper ones giving 

 rise to a few branches on the inner side, which may be several times 

 branched, the brauchlets slender, mostly erect and rather rigid. Spores 

 about 70 X 30 (i. Perithecia 120-1 GO X 35-45//, the crest-like tip 38- 

 45 (i broad, the appendage 12'i-.'] _*") «. Receptacle 85-120//. Append- 

 age, exclusive of branches 140-150//. Total length to tip of perithe- 

 cium 210-290 p. 



On Berosus striatus Say. Kittery Point, Maine. On margin of right 

 elytron towards the apex (invariably). 



EUZODIOMYCES nov. genus. 



Receptacle elongate, multicellular; consisting of a large and indefinite 

 number of cells superposed above the single basal cell and distally be- 

 coming divided by few or many longitudinal septa ; the distal portion 

 bearing a unilateral series of perithecia and appendages. Perithecia 

 with from nine to ten wall cells in each row, borne on a three-celled 

 stalk. 



Closely allied to Zodiomyces. Antheridia were not distinguished, the 

 material being scanty and in bad condition. 



Euzodiomyces Lathrobii nov. sp. 



Hyaline or faintly yellowish. Receptacle long and slender, or shorter 

 and stouter as in Zodiomyces, according as the longitudinal septa are few 

 or abundant ; the superposed cells and tiers of cells sometimes nearly 

 a hundred in number, the upper half or more producing a unilateral series 

 of perithecia and appendages. Perithecia distinctly broader distally, the 

 fourth or the fifth to the seventh wall cells inclusive, of two opposite 

 rows, growing upward and outward to form well developed prominences, 

 giving the margin on either side in this region a bluntly serrate appear- 

 ance; the lip-cells arched, forming a characteristic broad dome-like apex ;
