Klench. II, p. 68, is quoted as a synonym of Sphceria atramentosa, 

 Fr. in Kze. Myc. Hefte, 2, p. 38, and Fr. S. M. II, p. 344, is the same 

 as the Sphceria insidens, Schw. in Syn. Car. 122, and Fr. S. M. II, 

 p. 422, is not certain, but as far as the diagnoses go they may be the 

 -;imc; in that case the specific name, atramentosa, has precedence. 



H. colliculosum, (Schw.) 



Sphczria colliculosa, Schw. Syn. Car. No. 82. 

 Hypoxylon colliculosum, Cke. Syn. 1010. 

 Exsicc. (Rav. F. Am. 742)? 



Effused thin, colliculose, rugose, black. Perithecia very large, 

 covered with a thin crust which is papillate from the minute ostiola, 

 and with flattened bases not immersed in the wood or surrounded bv 



tj 



any circumscribing line, subdistant but connected by a stromatic 

 crust. Margin various, shining as if oiled, surface very uneven and 

 rimose. Sporidia 12-13 x 5 p (Cke.). 



On rotten oak wood, Carolina and Pennsylvania (Schw.). 



As already stated, the specimens in Rav. F. Am. do not agree 

 with the description of H. colliculosum, having both perithecia and 

 sporidia too small, and are probably referable to H. insidens, Schw. 

 We do not find any specimen of Sphceria colliculosa in Herb. Schw. 



H. illitum, (Schw.) 



Sphczria illita, Schw. Syn. N. Am. 1205. 

 Hypoxylon illitum, Sacc. Syll. 1511, Cke. Syn, 1014. 



Widely effused, confluent, the layers often superimposed, so as to 

 imitate a sculptured surface, the material of the stroma appearing as if 

 smeared on the decaying wood. Surface undulate and uneven, at first 

 of a fine olive-green, but finally black. Perithecia rather large, 

 slightly prominent, with ostiola indistinct or acutely conical and thick 

 walls, surrounded with a sparing white stroma. Sporidia fusoid, 

 navicular, very pale brown, acute, 10-12 x2J-3| // in spec, in Herb. 

 Schw, (14-16x4 {j., Cke.). 



Not infrequent on standing trunks, especially of Platanus, in- 

 vesting them almost completely with its broad, uneven, confluent 

 stromata, Bethlehem, Pa. (Schw.). 



H. investiens, (Schw,) 



Sph<zria investiens, Schw. Syn. N. A'm. 1210. 

 Hypoxylon investiens, Berk. Cuban Fungi, No. 837. 

 Exsicc. Rav. Fungi Car. IV, 33. 



Seated on a thick sterile crust that spreads over and blackens the 

 wood, following all the inequalities of its surface. On this crust stand, 

 densely crowded in a single series, the regularly oblong perithecia.
