43. IlYPOCiiEA PALLIDA, E. ^ E. 11 . s. Parasitic on decaying 
Polyporns caesius. Newfield, X. J. 
Perithecia pale horn-color, snbglobose (250 /^), immersed in a rather 
scanty, loose, white, tomentose mycelium (stroma), which overspreads 
the surface of the pores and covers the sides of the perithecia them¬ 
selves, leaving their apices and papilliform ostiola bare ; asci cylin¬ 
drical, 65—75 X 4—44 containing eight oblong-elliptical, 2-celled hya¬ 
line sporidia, the cells subcubical or nearly globose, 8 /^- in diam. and 
readily separating. The upper part of the perithecia collapses when dry, 
and, in old or weather-beaten specimens, the tomentose stroma disap¬ 
pears, leaving the perithecia sessile on the mouths of the pores. We 
have seen no specimens of H. pnlyporoidea, B. & C., but our species will 
be distinct from that, in the absence of any crust-like stroma and in its 
smaller sporidia. It was lirst found in October, 1880, and again in Octo¬ 
ber, 1886. 
44. IIypocrea corticticola, E. E. Journ. Mycol., I, p. 140. 
On bark of dead limbs of Magnolia glaum. Xewfield, N. J., August, 1885. 
Stroma thin, milk-white with the margin slightly cottony, forming 
a continuous layer, extending along the limb for six inches or more, 
finally becoming dirty-white, and cracking into small areas, as in Corti- 
chim polggonimn \ perithecia globose, pale, 75—100 p- in diam., buried 
in the stroma and visible under the lens as horn-colored specks; asci 
clavate-cylindrical, 20—22 x 3i p, sessile, without paraphyses sporidia 
biseriate, eight in an ascus, each consisting of two globose, hyaline cells, 
easily separating and 1—U /' (mostly 1 p- or a little over). This is closely 
allied to H. hyp)omyceUa, Sacc., Mich. I, p. 302, Syll. II, p. 529, but differs 
in its asci and sporidia being only about half as large as in- that species. 
45. riYPocREA POLYPOROIDEA, B. & Grev. IV, p. 15. Oil 
beech. Alabama, Peters, 6110. 
“ Peritheciis tomentosis, liberis, in crustara pallidam insidentibus. 
Fawn-colored; perithecia free, tomentose with a naked ostiolum, seated 
on a pale crust, liere and there elevated, which is thin towards the mar¬ 
gin. A very curious species.” Cooke, in Grev.. 1. c., gives the hyaline, 
snbglobose cells of the sporidia as 5 p in diam. 
C. Stroma diacoid. Sporidia continuous., hyaline. 
46. IIypocrea consimtlis. Ell. Grev.'XII, p. 79. X. A. F., 158. 
Stroma orbicular or elliptical, convex, 2—4 millim. across, brick-red, 
wrinkled, carnose ; asci clavate-cylindrical, 60—70 x 4 !»■; sporidia 1-ser- 
iate, hyaline, 10—12 x 34—4 P. On dead Azalea viscosa. Newlield, X. J. 
I). Stwma pulvinate or effused. Sporidia fusoid, hyaline., 1-septate. 
47. IIypocrea apiculata, ('.& P. 29th Bep.X. Y. State Mus., p. 57. 
‘‘Fleshy, soft, growing in irregular patches, smooth, ochraceous, 
inclining to orange, the extreme margin barren ; asci cylindrical ; spores 
fusiform with an apiculus at each end, l-septate, colorless, 27—37 x 74—10 
!>■. On the ground and on rocks. Catskill mountains, Xew York.”
