blackened on the surface. Perithecia evenly scattered, tolerably large, 

 monostichous, buried. Ostiola erumpent, subhemispherical, rough and 

 wrinkled or subcorneal at the apex, finally irregularly or sublaciniately 

 dehiscent, often obscurely quadrisulcate. Asci narrow-clavate, 30-40 

 x 5-7 fi (p. sp.), narrowed above. Sporidia biseriate, allantoid, yel- 

 lowish, moderately curved, 8-10 x 2 p.. 



On bark of poplar logs and limbs, Newfield, N. J., Illinois (Calk- 

 ins), Colorado (Cockcrell), Dakota (Williams). 



Eutypa subtecta (Fr.), found in Europe on Ace?- campestre and 

 A. pseudoplatanus is reported by Schweinitz as found at Bethlehem, 

 Pa. ("passim sub epiderm."), but he gives no definite host and there is 

 no spec, in Herb. Schw. Cryptosphceria millepimctata, Grev. is 

 found on Fraxinits, and has larger sporidia (14-18 x 3 p). 



Cr. fissicola, (C. & E.) 



Sphceria fissicola, C. & E. Grev. VI, p. 94. 

 Cryptosphceria fissicola, Sacc. Syll. 684, Cke. Syn. 4076. 



Perithecia scattered or subseriate, small, about J mm. diam.,sunk 

 in the surface of the inner bark, with their obtusely conical, perforated 

 ostiola barely erumpent through short, longitudinal cracks in the epi- 

 dermis; sometimes the ostiola of 3 or 4 perithecia lying near each other 

 on the same line, split the epidermis continuously for a centimeter or 

 more in length. Asci (p. sp.) oblong-fusoid, 20-22x4-5 //, short- 

 stipitate, aparaphysate. Sporidia crowded-biseriate, allantoid, slightly 

 curved, hyaline, 6-8 x 1| p,. 



On dead stems of rose bushes, Newfield, N. J. 



Cr. secreta, (C. & E.) 



Sphceria secreta, C. & E. Grev. V, p. 94. 

 Cryptosphceria secreta, Sacc. Syll. 688, Cke. Syn. 4079. 



Perithecia scattered, globose, \-\ mm. diam., covered by the epi- 

 dermis which is not at all pustulate, but merely pierced by the short- 

 cylindrical, obtusely-conical, perforated ostiola which do not rise above 

 the surface. Asci clavate, 40-45 x 7 ft, narrowed into a short, stipe- 

 like base and obtusely rounded above. Sporidia crowded, inordinate, 

 allantoid, only very slightly curved, hyaline, 8-10 x 1J-2 p, (10- 

 12 ;, Cke.). 



Under the epidermis of dead Viburnum lentago, Newfield, N. J. 



When the epidermis is peeled off, the perithecia come with it. 

 This is a very distinct and well marked species.
