Stroma erumpent-superficial, solitary or subconfluent, subglobose. 

 hemispherical or oblong, J-j cm. across, dull purplish-red, becoming 

 black, oravish-black within, roughened bv the distinctly prominent.

ovate, monostichous, fxj mm. perithecia. Asci (p. sp.i 7-~-80x 

 7-8 fjL. with abundant paraphyses. Sporidia uniseriate, opake. in- 

 equilaterally-elliptical, 10-12 x4J-5J /JL (12-14 x 6-6J t u, Sacc.). 



On bark of dead oak, Decorah, Iowa, and on bark of dead plum 

 trees, and (maple)? Vermilliou Lake. Minn. (Holway). 



According to Saccardo, the perithecia are larger and more promi- 

 nent than in the typical form, which is described by Xitschke as 

 having 1 the stroma pnlvinate, depressed, rarely hemispherical or nearly 

 globose, solitary or connate, with globose, crowded, subdistichous 

 peripherical perithecia, and sporidia 10-12x6^. The smaller stro- 

 ma ta resemble those of ff.fuscum, from which it is distinguished by 

 its smaller sporidia. From H. multiforme, it is distinguished by its 

 rather larger, darker spnridia.

Sphezria enteromela, Schw. Journ. Acad. Phila. Vol. V, p. 10. 



Stromata pulvinarc. often longitudinally confluent for six inclu- 

 iu length, rusty-red, suiiace not granulated, variable in shape, sub- 

 compressed, very black within, covered al)ove with a furfuraceous. 

 pulverulent, rust-colored bark. Immersed in the stroma are a few 

 perithecia of larger size, the others boinir minute, peripherical, globn-c 

 and black. The stroma stains the inner bark black. In the nature <>t 

 the outer layer of the stroma, this is allied to H. coccineum. Sec. 

 Cooke in Grev. XI, p. 123, the sporidia are 10 x 4 p. 



Erunipent from cracks in the bark of dead chestnut trees, Beth- 

 lehem, Pa. (Schw). Rather rare. 



H. Vera Criicis, Berk. & Cke. Grev. XI, p. 1 29. 



Subglobose, superficial, often confluent, 1-2 cm. diam., bright 

 rust-color, sooty black within. Perithecia of medium size, ovate, 

 peripherical, somewhat prominent. Asci cylindrical. Sporidia ellip- 

 tical, attenuated at each end. brown, 20x8 //. 



On rotten wood, Vera Cruz, Mexico (Salle). 



H. quadratum, (Sclnv,) 



Sphceria quadrata, Schw. Syn. N. Am. 1223. 



Stroma round, flattened-pulvinate, reddish-black, 2-3 mm. diam., 

 margin abrupt all round. Perithecia scarcely prominent. Ostiola 

 papilliform. Sporidia overlapping-uniseriate, brown, continuous, 15- 

 20 x 8-10 i.
