1894.] NATURAL, SCIENCES OF PHILADELPHIA. -^65 



ovate-elliptical, subinequilateral, abruptly narrowed at the euds, 

 3-5-septate, but not constricted, the inner cells nearly opake, the 

 small, terminal cells subhyaline, 12-15 x 6-8//.. 



The species is anomalous in the imperfectly developed perithecia, 

 the upper part soon falling away and leaving the cup- shaped base. 



Hendersonia falcata E. & E. 



On bark of fir trees, Exploits, Newfoundland, Dec. 1893 (Rev. 

 A. C. Waghorne, No. 10). 



Perithecia cespitose-erumpent, 6-10 together, united below in a thin 

 stroma, broadly perforated and subcollapsed above. Stromata small 

 (1 mm.), subconfluent and subseriately arranged. Sporules falcate, 

 more abruptly curved or bent above, yellowish-hyaline, granular, 

 becoming 1-3-septate, subattenuated below, on pedicels shorter than 

 the sporules, 20-22 x 5-7/'. 



Differs from Hendersonia rostrata S. & E. in its stroraatic growth 

 and broader, shorter sporules. 



Stagonospora petiolorum E. & E. 



On dead petioles of Aralia spinosa, Nuttallburg, West Va. , Feb. 

 1894 (L. W. Nuttall, No. 357). 



Perithecia scattered, innate, small, slightly prominent and covered 

 by the shining, blackened epidermis, 150-250,"- diam., mostly-sub- 

 elliptical. Sporules oblong, hyaline, nucleate, becoming 1-or more- 

 septate, 12-20x3-5,'/. 



Stagonospora Physocarpi E. & E. 



On dead stems and limbs of Physocarpas opnlifolius, Nuttallburg, 

 West Va., May, 1894 (L. W. Nuttall, No. 485). 



Perithecia scattered, depressed- hemispherical, 200-250,'/. diam., 

 sunk in the bark, with the upper part prominent but covered by the 

 epidermis which is pierced by the papilliform ostiolum, white inside. 

 Sporules linear, multiseptate, hyaline, 25-35 x 3-4,'/. 



Stagonospora Liriodendri E. & E. 



On decorticated wood of Liriodendron Talipifera, Alcove, N. Y., 

 June, 1893 (C. L. Spear, No., 304). 



Perithecia superficial, evenly scattered or 2-4 subconfluent, ob- 

 tusely conic-globose, about i mm. diam. Sporules cylindrical, 

 hyaline, 8-10 x 2-22,-/, nucleate but not visibly septate, though a 

 central nucleus causes them to appear uniseptate. Basidia slender 

 25-35,'/. long, profusely and subverticillately branched.
