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



Subiculuin inembranaceovis, thin, white, covered except the mar- 

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

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

 >ieon). 



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

 tion with more perfectly developed specimens. Seems different from 

 H. olivacea^ C. & E. 



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



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

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

 cyiindrical, 20-22 x3| ji, sessile, without paraphyses. Sporidia bi- 

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

 •easily separating and 1-1 J /* diam. (mostly 1 ji. or a little over). This is 

 ■closely allied to H. hypomycella, Sacc. Mich. I, p. 302, Syll. II, p. 529, 

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

 that species- 

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

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



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



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

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

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

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

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

 3^-4^x2-2 J fi. Outwardly this scarcely differs from H. corticiicola^ 

 E. & E., but the sporidia are very different, much like those of 7/. coic 

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



Parasitic on some thin Cofticiiim, on dead limbs of Lonicera 

 lying on the ground, Newiield, N. J. 



H. lactea, Pr. Summa. ^'eg. Seand. p. 383. 



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

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

 spoi-idia, globose, 3 /x 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 Polyporus medulla-panis and on the 

 ground.
