border, paler below. Perithecia few, scattered, convex-promiiieut. 

 Sporules oblong - elliptical, hyaline, 2-nucIeate, 4i-5i x 12-2/;. 

 Basidia simple, lanceolate- fusoid, 8-12 x H;/. 



Phyllosticta fragaricola Desm. has similar sporules, but (sec. specc. 

 in the various exsiccati), the spots are much smaller, with a white 

 center. The basidia also indicate Phoma and not Phyllosticta. 



Aposphaeria alpigena E. & E. 



On dead stems of Sambucus nielanocarpa, Cameron Pass, Colo., 

 July, 1894 (C. F. Baker). 



Perithecia scattered, superficial, globose or elliptical, 150-250/jt 

 diam., mostly depressed, obscurely papillate. Sporules elliptical, 

 hyaline, enucleate, S-Si x I^/j- 



Differs from A. fuscidula Sacc. in growing on the bark (not on 

 decorticated limbs), and in its smaller sporules. 



Aposphaeria pezizoides E. & E. 



On decorticated wood of Platanus, Liqvidambar, Fraxinus, Acer, 

 Salix nigra, and S. falcata, Nuttallburg, West Va., April. 1894 

 (L. W. Nuttall). 



Perithecia erum pent- superficial, seriate-aggregate, hemispherical, 

 about 4 mm. diam., with a distinct papilliform ostiolum, at length 

 collapsing and pezizoid or discoid. Sporules elliptical or ovoid, 4- 

 6 X 2^//, ends obtuse. 



This seems to grow exclusively on abrasions, below high- water 

 mark, made by driftwood on small trees. 

 Spliaeroiiema Physocarpi E. & E. 



On dead stems of Phy so carpus op rdifolitis, Nuttallburg, West Va., 

 May, 1894 (L. W. Nuttall, No. 484). 



Perithecia gregarious, erumpent-superficial, hemispherical, 150^ 

 diam., with a straight, stout beak 90-115// long. Sporules narrow- 

 elliptical, hyaline, 2-3-nucleate, 7-9 x 2hij.. 

 Sirococcus Halesiae E. & E. 



On dead limbs of Halesia tetraptera, Nuttallburg, West Va., 

 Feb. 1894 (L. W. Nuttall, No. 376). 



Perithecia scattered or 2-3-conuate, erumpent, subglobose, about 

 J mm. diam., black, with a minute papilliform ostiolum. Sporules 

 subglobose, about 3// diam., greenish-hyaline, 3-6-concatenate, the 

 terminal sporule oblong and paler. Chains simple, or sparingly 

 branched, arising directly from the proligerous layer without any 

 distinct basidia, collected in stellate clusters.
