Peritbecium relatively very long and large, yellowish, very slightly inflated toward the base, tapering 
very gradually die broad, blunt ti]> which is subtended by a truncate, conical lateral projection; the 
stalk-cell relatively short. Receptacle relatively small, the two cells nearly equal, the upper bearing 
the stalk-cell of the perithecium terminally and the basal cell of the appendage laterally; the latter over- 
lapping it to its base. Appendage consisting of four superposed cells, the basal (stalk-cell) small, triangu- 
lar; the two cells above it larj. r and longer, bearing short antheridial branches from the upper inner 
inirle the terminal cell smaller, subcorneal, bearing a small terminal branchlet. Spores about 44 X

A species most nearly related to S. occidrntalis, which occurs on Pinophilus in Utah but is small and 
differently shaped, and lacks the characteristic subterminal projection of the perithecium peculiar to the 
present species. The material is, for the most part, in bad condition, the branchlets of the antheridial 
appendages bring mostly broken, but its essential characters are shown with sufficient clearness.

Perithecium large, purplish, more or less distinctly curved away from the appendages, tapering 
below, often broader distally above the middle, tapering thence slightly to the tip, which is usually not 
distinctly differentiated; the apex small truncate or slightly papillate; the basal cells large, as long as or 
longer than the stalk-cell, dull amber-brown. Basal cell of receptacle large, not greatly elongated, taper- 
ing below, the nearly hyaline distal portion, obliquely distinguished from the deeply suffused, partly opaque 
portion of the cell below; the subbasal cell subtriangular. Appendage consisting of about five cells de- 
creasing in size from below upward, the septa nearly horizontal; those above the basal cell giving rise to a 
branch on the inner side, which in the subbasal cell and the cell above it consist of a very large broad 
basal evil, from which arise from two to four subhyaline branches which may be once branched, the 
branches crossing the stalk and basal cells of the perithecium obliquely, usually on the left side, so that 
urn lies at the left, the appendages lie above them. Spores 35 X 3.5 fi. Pcrithecia

This speci- is distinguished from other forms possessing a blackened basal cell, by the small unmodi- 
fied tip of its relatively very large perhheeium. It is perhaps most nearly allied to S. Brachyderi, but 
lacks the perithecial appendage of this species.
