diam., prolonged above into a filiform, subflexuous ostiolum nearly 

 1 nun. long. The perithecia contain an abundance of minute, hyaline, 

 oblong spermatia 4 x 1-1 \ //, often collected into a subglobose mass. 

 On pine lumber recently cut and closely packed, Newfield, N. J- 

 Doubtfully distinct from C. piliferum, (Fr.), which is also usually 

 sterile. 



C. piliferum, (Fr.) 



Sphceria pilifera, Fr. S. M. II, p. 472.

 Exsicc. Rab. F. E. 1525. 2327. 



Perithecia gregarious, naked, black, very small, globose, smooth. 

 Ostiolum capillary, very long, acuminate. Sporidia (sec. Berk. Grev. 

 IV, p. 146) sausage-shaped, 5 /x long. 



On pine rails, Carolina, on oak, Alabama. Found also in Penn- , 

 sylvania by Dr. Michener. 



C. mucronatum, (Schw.) 



Sphtzria mucronata, Schw. Syn. Car. No. 4. Fr. S. M. II, p. 475. 

 Ceratostoma mucronatum, Cke. Syn. 3814. 



Perithecia gregarious, minute, black, bare, conical, glabrous, some- 

 times confluent but not crowded, innate-superficial, smooth, rigid, con- 

 tracted above into a short-cylindrical, rather obtuse ostiolum. 



On dead wood, Carolina. Rare. 



C. drupivorum, (Schw.) 



Sphceria drupivora, Schw. Syn. N. Am. 1613. 

 Ceratostoma drupivorum, Cke. Syn. 3819. 



Perithecia rather large, hemispherical, densely crowded, black, 

 involved in a white, byssoid tomentum (which perhaps is only acci- 

 dental). Ostiola very long, dark liver-color, straight. 



On decaying nuts of Juglans cinerea, very rare, Bethlehem, Pa. 



C. investitum. (Schw.) 



Sphceria investiia, Schw. Syn. N. Am. 1621. 



Perithecia globose, rather large, at length free, black, at first 

 immersed in the wood and covered with tomentum. Ostiola large, 

 long, rigid, sulcate-tuberculose, thickened above, black. 



On rotten wood, emerging from a rather thick, cottony, brownish 

 rust-colored, or light yellow tomentum, with which it is entirely cov- 

 ered, /in other respects like C. rostrata.
