Stroma as in the preceding species, except that the central act- 

 uate portion is smaller, and, in well-grown specimens, the margin is 

 distinctly undulate and sublobate. Perithecia immersed, globose, or 

 subovate (150 y), scarcely roughening the surface, which is merely 

 punctate from the minute, slightly prominent ostiola. Asci cylindric- 

 al, 60-65 x 3 /i, without paraphyses, containing 8 two-celled sporidia 

 composed of two globose, hyaline cells, 3-3 \ y in diam., and readily 

 separable. On bark and wood, common. 



In the above synonyms we have included Sphceria riyens Fr. 

 (Sacc. Syll. II, p. 523) which is said to differ from H. Schweinitzii in 

 its smaller and more regularly-shaped stroma, with the perithecia con- 

 lined mostly to the central portion of the disc and by its habitat on 

 bare wood, and not on bark. The stroma is also said to be of a dark- 

 er color, without any olive or greenish shade. We are inclined to 

 think that these points of distinction are due to imperfect development 

 and are not of specific value, and we have examined many specimens, 

 as the species (as represented in N. A F. and Rav. F. Am.) is very 

 common, both around Newfield and West Chester. We have also re- 

 peatedly received from Carolina, Florida and Louisiana, specimens 

 of what is evidently the same as the "Hypocrea contorta" N. A. F. 

 156, but never anything that we could refer to the " Hypocrea, rigens, 

 (Fr.)" as distinct from H. Schweinitzii. 



H. chionea. E. & E. (in Herb.) 



Stromata gregarious, pulvinate, subhemispherical, 1-2 mm. diam., 

 snow-white, dotted with the minute, punctate, horn-colored ostiola. 

 Perithecia ovate, minute, horn-colored. Asci about 60x3 y. Sporidia 

 8 in an ascus, hyaline, two-celled, each cell 2J-3 y diam. 



On decaying, decorticated wood. London, Canada (Dearness). 



Differs from H lactea, Fr. in its pulvinate stroma. 



H. lati-zonata, Pk. 



Subiculum dirty-white, forming a broad (J-j cm.) band around 

 the outside of the cups of the Cyathus, thickly punctate with the 

 dark-brown, slightly prominent ostiola. Asci cylindrical, 75-80 x 3- 

 4 y, containing eight didymous sporidia, the cells separable, subglobose,
