ceptacle rather Blender, tapering to the base, consisting of (invariablj 

 ten Buperposed cells, exclusive of the foot-cell, which is not always 

 wholly blackeued. Appendage aa in C. roatraiiu, the numerous branches 

 and branchleta rather Blender, not verj Long, forming a rather compact 

 tufi more or less appressed around the base of the perithecium. Perithe-

Ceratomyces elephantinus nov. ip. 



Closely resembling C. denticulatus, rather faintly tinged with pale 

 amber brown, the neck proportionately Bomewhat broader; the upper 

 three sevenths to four ninths abruptly recurved, certain adjacent cells of 

 two opposite rows just below this curvature producing broad rather -hurt 

 blunt tooth-like outgrowths, one to two and three to four in each 

 respectively; the tip broad slightly and irregularly aulcate. Receptacle 

 consisting of from seventeen to twenty-two Bquarish or Battened cells, 

 sometimes hardly broader distally. Appendage producing numerous 

 long slender flexuous branches repeatedly branched. Perithecia, asci- 

 gerous part about 140 X Go ft, ueck to recurved part 475-525 u. re- 

 curved part 390-400 /.t. Spores 70 x 3.5 /j. Receptacle 375-ioO ft. 

 Longest branches of appendage 600 a.

Ceratomyces rhynchophorus nov. sp. 



Hyaline. Receptacle long slender, but slightly narrower below, con- 

 sisting of about forty (thirty-five to fifty) Buperposed cells, wider than 

 long ; those in the lower half more flattened, the foot small. Perithe- 

 cium lateral, nearly erect, slightly divergent ; a short but definite stalk- 

 cell ; the cells at the base greatly elongated, extending some distance up 

 around the ascus mass and forming together with the large elongated 

 supporting cell a broad sterile base t<> the perithecium which is not differ- 

 entiated I torn its main body: the cell rows consisting of but five cells, 

 including the very small lip-cells, and the cells of the sterile base : the 

 three upper tiers of cells forming an abruptly differentiated, thick walled, 

 long, tapering beak-like termination, curved outward or inward, often
