On legs of Limosina jerruginea St., No. 2528, Grand Etang, Grenada, 

 B. W. I. 



This species was found in abiuidance on hosts flying over dung on 

 the Grand Etang road. Although nondescript in appearance, it is of 

 interest for the reason that it belongs to a type transitional between 

 that of the more ordinary forms, and that of the group represented by 

 S. Limosinae and its allies, to which it is very evidently nearly related. 



Stigmatomyces pentandrus nov. sp. 



Receptacle relatively long and stout, subhyaline, of nearly uniform 

 diameter throughout, slightly broader in the region of the horizontal 

 septum ; the walls unusually thick, the basal cell usually shorter than 

 the subbasal. Stalk-cell of the appendage somewhat obliquely in- 

 serted on the protruding outer angle of the subbasal cell, rather deeply 

 suffused with amber-brown, concolorous with the venter of the peri- 

 thecium, narrow, its outer margin strongly concave, slightly prominent 

 and rounded below the insertion of the short, straight, slightly tapering 

 appendage. Appendage consisting of two cells, the basal hardly 

 longer than broad and bearing two antheridia; while the subbasal 

 bears but one, and is succeeded by two superposed antheridia, the 

 terminal one erect and bearing a stout spine. Stalk-cell of the peri- 

 thecium somewhat larger than the cells above it, and less deeply 

 colored than the flattened basal cells; the whole region, including the 

 stalk-cell of the appendage, relatively short, abruptly narrower than 

 the distal end of the receptacle, and forming a slight constriction, 

 thence expanding almost symmetrically upward to the venter of the 

 perithecium; which is relatively very short and broad, symmetrically 

 inflated; its surface, as well as that of the neck and at maturity even 

 the tip, indistinctly and evenly granular; dis tally narrower and at 

 once abruptly broader at its junction with the broadly, but not 

 abruptly, spreading base of the neck; which is distinctly longer, 

 stout, slightly paler, its distal half of uniform diameter, but abruptly
