138 THAXTER. — MONOGRAPH OF THE LABOULBENIACE^}. 
This fine and very distinct species has been seen on two specimens, only, of its host, taken in Lake 
Bust is. It is distinguished by the great size of its perithecium, and especially of its primary appendage, 
the branches of which are more numerous than those of any other species. It sigmoid curvature and 
ptle mlor serve further to distinguish it.

Dark amber-brown. iVritheeium somewhat inflated just above the constricted base, the upper 
two-tliirds broad and of about the same diameter throughout; about forty-five wall-cells in each row, the 
tip small, short, rather narrow, abruptly hunched externally, the hyaline lips turned abruptly toward 
the base of the perithecia] appendage, which consists of a basal cell hardly differentiated from the wall- 
.11 bdow it. though somewhat longer, the portion above it erect, slender, stiff, slightly curved outward, 
tapering but little, the subbasal cell bearing a characteristic basal enlargement which projects toward 
be lip- Ik and lies just above them. The appendage and receptacle much as in C. mirabilis. Perithe-

this is decidedly the largest species of the genus, with the possible exception of C. curvatus, and is 
readily distinguished by the conformation of its tip, which resembles that of C. Mexicanus, and by the 
blunt projection from the base of the perithecial appendage just opposite the apex of the perithecium.

Amber-brown. Receptacle relatively slender, consisting of three small superposed cells surmounted 
by two similar cells which form the base of the appendage and perithecium; the foot small, normal. Peri-

i"ak-l.keapex,sothat the inner margin of the tip is thus horizontal, or even oblique, above the apex;
