Cryptosphaeria paetula (Fr.). 



Sphceria pcetula Fr., S. M., II, p. 483. 

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



Crytosphceria secreta (C. & E.) Sacc, Syll., No. 688, and Ell. & Evrht., N. A. 

 Pyr., p. 514. 



The Schweinitziau spec, shows no asci, but the perithecia, habit, 



and sporidia are the same as in Sphceria secreta, C. & E. , leaving no 



doubt that the latter is the same as Sphceria pcetula (Fr. ) if, as 



seems probable, the spec, in Herb. Schw. is reliable. 



Pseudovalsa occulta (Schw.) 

 Sphceria occulta in Herb. Schw. 



Stroma cortical, orbicular, not circumscribed, 2-3 mm. diam., 

 convex. Perithecia 1-5 in a stroma, f-1 mm. diam., globose, their 

 bases slightly sunk in the surface of the wood, ascigerous nucleus 

 light colored. Ostiola obscure, erumpent in a small black disk, 

 which is orbicular or narrowly and transversely elliptical, slightly 

 raising and perforating the epidermis and closely embraced by it. 

 Asci broad clavate-cylindrical, 180-210 x 20-30// (including the 

 very short stipe, 8-spored, with filiform, sparingly branched or mostly 

 simple paraphyses. Sporidia biseriate, broad-fusoid-oblong, obtuse, 

 3-septate, 45-62 x 13-16//, hyaline, becoming brownish. 



Differs from P. malbrancheana Sacc. in its 8-spored asci and only 



3-septate sporidia not hyaline at the ends. 



Diatrypella obscurata (Schw.). 



Sphceria obscurata Schw. (in Herb.). 



Perithecia large (f mm.), either lying singly, or 2-6 together in 



a subcuticular stroma 2-6 mm. diam., black and rough outside, 



white within, blackening the surface of the wood which is also deeply 



penetrated by a dark, circumscribing line enclosing several stromata. 



Asci clavate, 75-80 x 12-15//., p. sp. about 50//, long, polysporous. 



Sporidia irregularly crowded, yellow in the mass, hyaline when seen 



singly, allantoid, moderately curved, with a nucleus near each end, 



5-6 x 1}//. 



On limbs of some shrub or tree, Bethlehem, Pa. , Schw. 



Hypoxylon annulatum (Schw.) Mont. 



Sphceria annulata Schw. in litteris ad Fries. See Fr. Elench., II, p. 64. 



Sphceria annulata B. depressa Fr., 1. c. 



Sphceria truncata Schw. in litt. Fr. Elech., 1. c, but (sec. Fries) not Sphceria 



truncata Schw. in Syn. Car. 

 Hypoxylon amtulalum Mont., Syll. Crypt., p. 213. 



The spec, of Sphceria truncata Schw. from Herb. Schw. agrees 

 perfectly with specc. of Hypoxylon annulatum distributed in Ell. & 

 Evrht' sN. Am. Fungi, 2d Series, 2,353.
