veral perithecia and simple sterile appendages. Perithecia asymmetrical; spores 

 indistinctly septale." 



Amorpliomyces n. gen. 



„Sexual Organs boron separate individuals. 



Male individual. Receptacle consistiug of a few superposed cells, without 

 true appendages, bearing terminally a Single large perithecium. Asci arising 

 from a lateral placenta-like ascogenic area." 



Hajylomyces n. gen. 



„Beceptacle consisting of two smals superposed cells from which arise 

 the Single perithecium and the single antheridial appendage. Perithecium large, 

 pointed, borne on a Single stalk cell surmounted by twe basal cells. Anthe- 

 ridial appendage consisting of a basal cell sour mounted by a terminal body, 

 the antheridium, divided by anastomosing septa into numerous small cells and 

 fournished with a short lateral projection together with a subterminal, hört 

 spine-like process arising from a rounded base. Asci four spored, arising from 

 four main ascogenic centres, each of wich is divided into two secondary centres. 

 A very simple type, without sterile appendages, nearly allied to Cantharomyces 

 by the presence of highl}- developed cellular antheridium, which in the lather 

 genus is lateral injjosition and without the characteristic thorn-like tip." 



Idiomyces n. gen. 



„Receptacle short; flattened, terminated on one side by a series of super- 

 posed cells bearing externally a vertical row of closely set appendages, on the 

 opposite side by one or moi'e stalked perethecia at the base of which or one 

 side arise s a second transverse series of similär appendages. Perithecia straight, 

 symmetrical, borne on a stalk composed of a single basal and several terminal 

 cells. Appendages consisting of a series of antheridial cells, their projecting 

 necks forraing a comb-like appendage which may be terminated by short 

 branches. Spores as in other geuera." 



Chaetomyces n. gon. 



„Receptacle slender, consisting of numerous superposed cells from which 

 arise successively the appendages and one or more perithecia in a unilateral 

 series. Perithecium flattened, the symmetrical apex prominent, borne on two 

 stalk cells surmounted by several basal cells. Fertile appendages arising from 

 cells of the receptacle immediately below the perithecium ; sterile appendages 

 arising from its terminal cells. Spores as in other genera." 



Rhadinomyces n. gen 



„Receptacle consisting of two superposed cells, from the upper of which 

 arise one to several stalked perithecia and a antheridias appendage. The ap- 

 pendage consisting of a several superposed cells each of which may bear from 

 its distal and one or more shorte fertile branches produciug flask-5 haped anthe- 

 ridia more or iess irregularly : the distal cell of the series terminated by one 

 or more long sterile branches. Perithecia subconical, borne on a shalk made 

 up of a Single basal cell sur monnted by several smaller bells. Spores as 

 in otlier genera " 



Teratomyces u. gen. 



„Receptacle consisting of several superposed cells surmounted by a series 

 of smaller cells which sourround certain central cells, from which the perithecia 

 arise, and produce distally a circle of appendages from within which the long 

 stalked perithecium is exserted. Perithecia one or more in number, symmetrical, 

 the stalk consisting of on elongate basal and three distal cells. Appendages 

 consisting of one or more superposed cells , each producing externally a single 

 row of branches. Spores as in other genera." • 



Dicliomyces n. gen. 



„Receptacle flattened, bilaterally symmetrical, multicellular above a narrow 

 stalk cell, terminated by two clearly defined transverse rows of cells; the sub- 

 terminal cells of the lowes row modified to form, anteriorly, single projectinjj 

 tooth-like antheridia : the upper series bearing a pair of perithecia and several 

 sterile appendage all symmetrically arranged. Appendages as in PeirüscMella, 

 simple, cylindrical. Perithecia symmetrical."
