Elencli. II, p. 68, is quoted as a synonym of SphcBria atramentosa, 

 Fr. in Kze'. Myc. Hefte, 2, p. 38, and Pr. 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 

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



H. colliculosum, (Schw.) 



SphcEria colHculosa, Schw. Syn. Car. No. 82. 

 Bypoxylon colliculosum, Cke. Syn. loio. 

 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 by 

 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 j« (Cke.). 



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



As already stated, the specimens in Rav. P. 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 Sphoeria colliculosa in Herb. Schw. 



H. illitum, (Schw.) 



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

 Hypoxylon illitum, Sacc. Syll. 151 1, Cke. Syn, 1014. 



Widely efiiised, 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 x2|-3^ // in spec, in Herb. 

 Schw. (14-16 X 4 /i, Cke.). 



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

 vesting them almost completely with its broad, uneven, confluent 

 stromata, Bethlehem, Pa. (Schw.). 



H. inv^stiens, (Schw.) 



SphcEria investiens, Schw. Syn- N. Am. 1210. 

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

 Fxsicc. 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
