of the subbasal cell, which is also continuous with a similarly blackened 

 branch, the whole forming a black outcurved or even recurved process 

 from the convex side of which one or two hyaline erect branches or 

 branchlets arise. Secondary receptacles variously developed, typi- 

 cally two, growing in opposite directions, rather slender and usually 

 curved; their basal cells short, and giving rise at once to the first 

 perithecium and antheridial appendage; the second much longer, 

 bearing the second perithecium and antheridium distally; the third 

 still longer and usually terminated by two antheridia. In less well 

 developed specimens only one branch may develop, with a single 

 perithecium and antheridium; or both, if developed, may be much 

 shorter and the habit more compact. Perithecia somewhat variable, 

 typically with a well developed stalk-cell, which is narrower in the 

 middle and broader distally than the small compact basal cell-region 

 of the perithecium; which is abruptly distinguished, also, from the 

 suddenly inflated venter above ; the venter short, the rest of the body 

 long, tapering evenly to the blunt point, the junctions of the wall- 

 cells indicated by two successive elevations by which a neck and tip 

 are distinguished. Antheridia relatively long and slender, the basal 

 cell-pair and the subbasal about equal; the cells of the two antheri- 

 dial pairs bulging distally so that this portion of the antheridium is 

 marked by successive elevations and depressions; the distal cells 

 giving rise to from two to four usually curved rather short branches.

The short compact forms occur on the legs, the more highly de- 

 veloped specimens on the abdomen and elsewhere. Although not 

 departing widely from the usual type this species does not appear to 

 be nearly allied to any other form, when well developed. 



Monoicomyces Amauroderae nov. sp. 



Hyaline, except for the brownish yellow perithecia. Basal and 

 subbasal cells about equal in size, hardly longer than broad; the 

 primary appendage simple, consisting of five or six superposed cells; 

 the basal cell bent abruptly upward from the receptacle, and distin- 

 guished by a small !)lack septum. Fertile branches typically two
