[Vol. IV, No. 9, 
271). On an old log, Louisiana (Langlois 743.) On fallen logs, 
So, Ca. (Ravenel F. Am. 649.) Effused, black, crustaceous, thin 
(1—1J mm.), papillose from the prominent ostiola, 3—5 or more 
cm. broad, originating beneath the cuticle of the bark which it 
throws off in the same manner as Nummularia Bulliardi Tub, 
which it much resembles. Asci linear-cylindrical. Sporidia 
uniseriatc elliptical with the ends subacute, sometimes navicular, 
dark, 28 x 8 micr. (sec. Cke)—20—23 x 10—12 in the La. specc. 
20—25 x 10—12 in the F. Am. specc. 
Hypoxylon epirhodium, B. & Rav. Grey. IX, p. 51.—On 
branches of rose. South Carolina, (Ravencl). “Effused, thin, form¬ 
ing small black patches about two lines across, papillose from the 
slightly prominent ostiola; asci linear; sporidia uniseriate, elliptic. 77 
Sporidia sec. Cke. 1. c. 9 x 3| micr. 
Hypoxylon punctulatum, B. & Rav. (sub Diatrype) Grev. IV, 
p. 94. Nummularia punctulata (B. & Rav.) Sacc. in Syll. On bark 
of dead oak. Common. Originating beneath the cuticle which is 
soon thrown off, closely adnate, black, smooth and polished, effused 
and spreading for 5—20 cm. or more, but not projecting above 
the bark, ostiola punctiform, depressed, appearing like minute 
punctures made with the point of a pin, margin sterile, thin. Per- 
itfiecia monostichous, elongated-ovoid rather more than § mm. 
high, covered above by the thin carbonaceous stroma. Asci 
cylindrical with a slender base, 100 x 7 micr. with filiform para- 
physes, (p. sp. 75—80 micr. long,) Sporidia uniseriate, elliptical, 
yellowish-hyaline, 2-nucleate, 7—8 x 5, ends flattened while lying 
in the asci. We have not seen them free and cannot say whether 
they become opake. The asci and sporidia are generally poorly 
developed but Mr. Everhart finds them as above noted at V r est 
Chester. 
Hypoxylon tinctor, (Berk.) Hook, Lond. Journ. Bot IV, p. 311. 
— On dead trunks and limbs of various deciduous trees from Ohio 
west to Kansas and south to Louisiana, Florida and Texas. Stroma 
effused, dull black, very hard, exhibiting all the inequalities of the 
matrix, 1 mm. thick, 5—20 cm. long and 2—5 cm. wide, margin 
thin and sterile, surface nearly smooth but under the lens distinctly 
papillose from the slightly prominent ostiola. The subjacent wood 
is deeply tinged orange red and is rendered very hard. Perithecia 
monostichous, crowded, elongated (J mm,) covered above with the 
hard brittle shining black stromatic layer, Asci 112 (p. sp. 90— 
100) x 7—8 micr. with abundant filiform paraphyses. Sporidia 
uniseriate, pale brown with a single rather large nucleus, oblong- 
navicular, 15 x 6 micr. with the ends subobtuse. The stroma
