in the long stalked forms, associated throughout with shorter appendages 

 and antheridia. Some of the individuals on A. Lespezi small, the main 

 axis of the receptacle consisting of only seven cellsj the perithecia nearly 

 sessile and small in proportion. Spores 50-60 X 4 //. Perithecia 140- 

 150 X 45—69 fi (100 X 30 ju in small specimens), the stalk including basal 

 cells longest 220 X 47 ^. Total length to tip of peritheciam about 550 ^ 

 (200-680 /i). Receptacle 325 ^u (1 10-350 ,«). Appendages longest 

 400//.

Compsomyces Lestevi nov. sp. 



Receptacle consisting of a small basal and subbasal cell, the latter giv- 

 ing rise to rarely more than two branches ; one of which consists of a 

 basal cell, from the upper side of which the stalk-cell of the perithecium 

 arises; while externally it gives rise to a characteristic sterile branch, 

 simple, usually slightly upcurved, rather closely and somewhat obliquely 

 septate, commonly consisthig of about nine superposed cells tapering 

 rather abruptly at the tip. Perithecium borne on a well developed erect 

 stalk-cell, nearly symmetrical, tapering from about the middle to the 

 broad truncate undifferentiated tip ; the basal cells small, but slightly 

 distinguished from the inflated base of the ascigerous portion, the spores 

 few and relatively large. The other branch arising from the subbasal 

 cell of the receptacle, an antheridial branch, divergent, consisting typically 

 of four superposed cells above which it becomes furcate, dividing into 

 two branches which iire large stout tapering, distally curved ; the third 

 cell of the appendage producing a single short flask-shaped autheridium 

 distally on its inner side and sometimes giving rise to a branch similar to 

 those above. Spores 42 X 4^/. Perithecia 75-85 X 30-35 ju, the stalk 

 75 X 22 fi. Antheridial appendage including branches 275 ^, the basal 

 part about 60 X 20 ju.

CLEMATOMYCES nov. genus. 



Receptacle consisting of a basal and a subbasal cell from which arises 

 distally a main axis bearing a terminal perithecium and formed by a double 

 row of cells ; the cells of the external row producing sterile appendages,
