24 ERYTHEA. 



epidermis, but not erumpent. Sporules oblong-elliptical, 

 brown, 20-22x7-8>w. 



Haplosporella Telata. On dead stems of Celastrus scan- 

 dens, Jan., 1895 (No. 1648). 



Stromata orbicular, or elliptical, obtusely conical, slaty 

 black inside, raising the epidermis into distinct pustules 

 which are cleft across the summit, the open cleft being filled 

 with gray, fine granular matter. Perithecia reduced to mere 

 light-colored cells in the substance of the stroma. Sporules 

 oblong, obtuse, continuous, brown, 12-16x5-6/^. The bark 

 around the stroma is not at all blackened, but rather whitened 

 or bleached. 



Diplodia lopliiostomoides. On decorticated limbs of 

 Negundo aceroides, July, 1895 (Bartholomew, No. 1780). 



Perithecia gregarious, at first covered by the loosened 

 fibers of the wood, then erumpent, globose or elliptical, ^ 

 mm. diam., or ^x^ mm., ostiolum often slightly compressed. 

 Sporules oblong, elliptical, 15-20x6-7/^, uniseptate, scarcely 

 constricted. 



Diplodia (?) subterranea. On a pine post below the sur- 

 face of the ground, Jan. 10, 1895 (No. 1652). 



Perithecia erumpent, superficial, ^-| mm. diam., subas- 

 tomous, with very thin membranous walls which soon fall 

 away, leaving a mass of brown, elliptical uniseptate con- 

 stricted spores, 6-8x3|-4/^. No basidia seen. 



The thin-walled perithecia and the pulverulent mass of 

 spores make this an abnormal species if, in fact, it should be 

 called a Diplodia. 



Diplodia clavispora. On decaying wood of an old elm 

 stump, May, 1894 (No. 1475). 



Perithecia erumpent, superficial, closely gregarious, coni- 

 cal, rough, black, about 200xl00yU diam. Sporules wedge- 

 shaped, brown, uniseptate, and slightly constricted, 6-8x3- 

 3|//. Some of the perithecia contain minute Phoma spores. 



Diplodiella striispora. On decorticated cottonwood 

 stump, Jan., 1894 (No. 1356).
