globose, with a papilliform ostiolum soon perforated, seated on a red 

 subicnlurn and clothed with a thin, dirty rose-colored, pulveraceo- 

 tomentose coat. The mycelium is very thin and scanty and the 

 wood is stained red in the part occupied by the perithecia. The 

 substance of the perithecia themselves also has a reddish tint. Asci 

 cylindrical, p. sp. 68-75 x 8//, short-stipitate, 8-spored, paraphy- 

 sate. Sporidia uniseriate, elliptical or subglobose, opake, 8-12 x 

 5-7/*. 



Rosellinia imposita Schw. 



Sphceria imposita Schw., Syn. N. Am., 1,503. 



This differs from R. aquila only in the scanty subiculum. 



Sporidia oblong, continuous, brown, 18-24 x 6-8/./.. 



Ceratostomella investita (Schw.). 



Sphceria investita Schw., in Herb. Fries. 

 Sphceria investita in Schw. Syn. N. Am., 1,621? 

 Sphceria vestita Schw., in Herb. Schw. 

 Ceratostomella investita Starbiick, 1. c. 



Perithecia gregarious, immersed, or partly superficial, 400//diam., 

 beset around the lower part with slender, black, septate hairs 80-120 

 x 3fi, and pubescent with shorter, finer hairs above. Ostiola cylin- 

 drical, 1 mm. or more long, erumpent through a felt-like brownish- 

 yellow tomentum overspreading the surface of the wood. 



Asci cylindrical, 60-65 x 6-7//, with a short stipe, p. sp. 50-60// 

 long. Paraphyses none. Sporidia uniseriate, or subbiseriate above, 

 oblong-elliptical, 6-8 x 3?//, hyaline, 2-nucleate. 



There can be no doubt that this is the same as the spec, examined 

 by Starbiick, in Herb. Fries, but it does not agree entirely with the 

 diagnosis given by Schweinitz, as the ostiola are not "sulcate-tuber- 

 culose," nor are they " thickened above. " The spec, from Herb. 

 Schw. was labeled " Sphceria vestita" L. v. S., and was on rotten 

 wood, Bethlehem Pa., "vestita" being apparently a lapsus calami 

 for investita. 



Amphisphaeria papilla (Schw.). 



Sphceria papilla Schw., Syn. Car., 159. 

 Melanopsamma papilla (Schw.), N. A. Pyr., p. 17S. 



Perithecia conic- hemispherical, with the base slightly sunk in the 

 wood, f-1 mm. diam. with a distinct conic- papilliform ostiolum. Asci 

 cylindrical, short-stipitate, paraphysate, p. sp. 100-120 x 12-15//.. 

 Sporidia overlapping- uniseriate, fusoid- oblong, subinequilateral, 

 brown, uniseptate, slightly constricted, 25-32 x 8-1 2,u. 



On rotten wood, Bethlehem, Pa.
