and l(i /x at base; the apex about 20 X 12 /x. Appendage 55-65 yu. 

 Receptacle 42-44 X lo^t. Total length to tip of perithecium 155-

On the legs of Limosina puuciipennis Wied. Xo. 2(553, Kamerun, 

 W. Africa. 



This species is most nearly allied to 8. proHferans, the appendage 

 being similar and occasionally showing a similar prohferation distally. 

 In other respects, however, its appearance is very different, owing to 

 its short receptacle, distally expanded venter, and larger, abruptly 

 distinguished, somewhat inflated apex. 



Stigmatomyces proliferans nov. sp. 



Usually straight and rather slender, pale yellow, especially the 

 venter; the receptacle hyaline; the base of the appendage tinged 

 with amber-brown. Receptacle usually comprising nearly half the 

 total length, the basal and subbasal cells of nearly equal diameter, 

 the latter often slightly longer, and distally somewhat broader than 

 the region immediately above it. Stalk-cell of the appendage re- 

 latively small, liut slightly longer than broad, externally straight, or 

 slightly concave, slightly and abruptly prominent below the rather 

 broad insertion, which lies somewhat lower than the base of the 

 ascigerous cavity; axis of the appendage consisting of usually seven 

 obliquely superposed, successively smaller cells; the uppermost 

 forming a minute erect, free, blunt projection; the basal cell hardly 

 longer than broad, tinged with amber brown, the outer margin nearly 

 straight, that of the three cells above it very strongly convex; all, 

 except the uppermost, bearing single antheridia on the inner side, 

 which are appressed and very obliquely superposed in a single row, 

 long and slender, the neck and venter hardly distinguished; the 

 upper two or three, including also the minute terminal cell, finally 

 proliferous, producing partly dichotomous slender rigid branches, 

 which form a variably developed coralloid group, their tips swollen 

 and eventually separated (as sperm cells?) in a gelatinous mass. 

 Stalk-cell and secondary stalk-cell of the perithecium longer than 

 broad, overlapping laterally, nearly equal, the latter higher; the basal 

 cells almost as large, and overlapping the ascigerous cavity above, 

 the outer externally concave, and distally slightly prominent. Peri- 

 thecium erect, rather slender, the distal portion somewhat longer 

 than the slightly inflated venter, which tapers rather abruptly above
