 H. melalehca, E. & E. Proc. Phila. Acad. .July, 1890. 



Subiculum membranaceous, thin, white, covered except the mar- 

 gin with a single layer of minute (110-130 ;i), slate-colored perithecia 

 filled with globose sporidia? (or perhaps stylospores, as no asci were 



seen). 



This seems to be a distinct species, but requires farther observa- 

 tion with more perfectly developed specimens. Seems different from 

 H. oliimcea, C. & E. 



H. corticiicola, E. & E. Journ. Mycol. I, p. 140, (Plate 11) 



Perithecia globose, pale, 75-100 fi diam., buried in the stroma 

 and visible under the lens as horn-colored specks. Asci clavate- 

 cylindrical, 20-22 x3| ft, sessile, without paraphyses. Sporidia bi- 

 seriate, eight in an ascus, each consisting of two globose, hyaline cells, 

 easily separating and 1-1 u diam. (mostly 1 ft or a little over). This is 

 closely allied to H. hypomycdla, Sacc. Mich. 1, p. 302, Syll. II, p. 529. 

 but differs in its asci and sporidia being only about half as large as in 

 that species. 



Parasitic on Corticium scutellare, B. <fe C.,or some closely allied 

 species, on dead limbs of Magnolia and oak, Newfield, N. J. 



H. subcarnea, E. & E. Journ. Mycol. Ill, p. 114. 



Perithecia carnose. pale, minute (80 /*), buried and barely visible 

 under the lens as minute specks, giving the surface of the Corticium 

 a punctate appearance. Asci subcylindrical, sessile, without paraph- 

 yses, 30-35x5-7 ft. Sporidia uniseriate or partly biseriate above 

 subhyaline (with a yellowish tint), oblong-elliptical, 1-2-nucleate. 

 3J-4Jx2-2| fi. Outwardly this scarcely differs from H. corticiicola. 

 E. <fc E., but the sporidia are very different, much like those of //. con- 

 similis, Ell., from which, however, it is quite distinct. 



Parasitic on some thin Corticium. on dead limbs of Lonicera 

 lying on the ground, Newfield, N. J. 



H. hictea, Fr. Summa. Veg. Scand. p. 383. 



" Carnose, broadly effused, bare, milk white, ostiola punctifonn. 

 Asci cylindrical, 56x4 /i, subequal cells of the didymous, hyaline 

 sporidia, globose, 3 fi diam." In Sacc. Syll. II, p. 529, the species is 



credited to North America. We have seen no specimens. The habitat 

 is given as on rotten wood, on Polypon/s medulla-pants and on the 

 ground.
