depressed, as in Rypoxylon punctulatum , the opening at first filled with 
white farinaceous matter. Perithecia ovate-globose, small (less than one- 
half millimeter), monostichous. Asci (p. sp.) about 25 by 3/*, or with 
the short base 45-50/* long. Sporidia uniseriate, ends mostly slightly 
overlapping, sub-inequilaterally elliptical pale brown, 4.J-5 by 2-2£/*. 
Berkeley says N. hypophlcca has larger ostiola and narrower sporidia. 
This is true as to, the ostiola, but as regards the sporidia the case is ex¬ 
actly the opposite. The wood beneath the stroma is stained with the 
same olive yellow color as the next species to which this is closely allied, 
but differs as stated. 
Nummular la iiypophl^ea, (B. & Bay.) Grev. IV, p. 05, ibid. XU, p. 
7. Anthostoma hypophlceum , Sacc. On dead trunks of Magnolia glanca , 
New field, X. J. (Ellis), South Carolina (Ravenel). Stroma thin, subor- 
bicular J-l cm across, slate color, originating beneath the cuticle, 
which is soon thrown off, slightly convex, and faintly papillose from the 
slightly projecting ostiola. Stains the subjacent wood yellowish or yel¬ 
lowish olive. Perithecia in a single layer, ovate-globose, small (one-half 
millimeter), abruptly contracted above into a slender neck piercing the 
superficial carbonaceous layer of the stroma. Asci slender (100 by 4/*) 
with a thread-like base (p. sp. 55-GO/* long). Sporidia uniseriate, 
lying mostly end to end, narrow, elliptical, pale brown, 2 nucleate, about 
7 by 2£-3/*. 
Xummularia rumpens, Cke. Grev. xii, p. 8 . Diatrype rumpens, 
Cke. Ann. X. Y. Acad. Sci., I, p. 185. On bark, Galveston Bay, Texas 
(Ravenel). Orbicular or elliptical ^-l cm in diameter or by confluence 2 cm 
or over, and then more or less irregular in shape, thin, black, surrounded 
by the ruptured epidermis, roughened by the slightly prominent ostiola. 
Perithecia monostichous, ovate, f millimeter high. Asci cylindrical, 
100-115 by 10 //. Sporidia uniseriate, hyaline, then opaque, elliptical, 
with ends sub-acute or rounded, 12-15 by 7-9//. This description is 
drawn from the specimens in Raw F. Am. This seems to differ from N. 
Bulliardi in its less prominent ostiola and rather more acutely pointed 
sporidia 5 nor are there in the specimens we have seen any very percep¬ 
tible remains of the overlying membrane. In our collections are speci¬ 
mens of what appears to be the same as those in F. Am. from British 
Columbia and Louisiana, as well as several of the original Texas speci¬ 
mens from Dr. Ravenel. 
Xummularia exutans, Cke. 1. c. Broadly effused, black, sub-cutic- 
ular, soon erumpent, thin (about one-half millimeter) papillose from the 
slightly prominent ostiola. u Two or three inches long, with an irregular 
outline, thinner than N. rumpens P Perithecia monostichous, depressed 
globose, less than one-half millimeter in diameter. In our specimen of this 
species from Dr. Ravenel, from his Texas collection, the asci had disap¬ 
peared. The free sporidia were acutely elliptical or almond shaped, 
rather variable in size, 10-15 by G- 8 //. Cooke saysostiola depressed.” 
In Ravenel’s specimen they were as noted above; presenting the same
