Herpomyces Ectobiae nov. sp. 



Male individual consisting of four superposed cells terminated by the 

 characteristic blackish projection, the distal cells producing a dense ap- 

 pressed tuft of coherent antheridial branchlets and antheridia ; the sub- 

 basal cell usually giving rise to a fertile branch, simple or furcate, which 

 produces a secondary male receptacle consisting of an irregularly double 

 straggling series of cells, some of which are sterile, while others bear 

 short-stalked, unilateral, dense antheridial tufts similar to the primary 

 one (which may sometimes be lacking ?). 



Female individual colorless. Primary receptacle as in the male, ter- 

 minated by two short cells, the upper of which bears distally the charac- 

 teristic blackish minute foot-like projection, the subbasal cell producing a 

 simple or furcate fertile branch. The fertile receptacles, like those of 

 the male, often creeping extensively, consisting of an irregularly double 

 series of obliquely seriate cells, sterile or fertile without definite sequence, 

 the whole plant producing sometimes twelve or even more perithecia 

 developed as a rule in irregularly acropetal succession. Perithecia sub- 

 sessile, inflated below, attenuated above, the extremity bent or sometimes 

 slightly recurved, the apex unmodified. Spores 20 X 2.5 /n. Perithecia, 

 including base, 80-90 X 20 it. Total length of secondary receptacle, 

 longer, 200-225 X 15 it. Primary individual 22 it. 



On Ectobia Germanica Scudd., Cambridge, Mr. Bullard. On Ectobia 

 sp., Zanzibar; Mus. Comp. Zool., No. 1357: St. Kitts, West Indies; 

 Mus. Comp. Zool., No. 1361. Although aberrant from the fact that the 

 male develops secondary receptacles, this species corresponds exactly to 

 the generic type in all other respects.
