Stroma effused, black within and without, colliculose and uneven 
from being composed apparently of many smaller stromata 3—10 
mm. in diam. fused together laterally more or less perfectly into a 
continuous or partially interrupted crust irregular in outline and 
several centimeters in extent. Perithecia subglobose, J— J mm. 
diam. their apices slightly prominent with a subacute papilliform 
ostiolum surrounded by an indistinct lighter colored ring which 
however is not impressed or sunk into the stroma as in H. annu- 
latum. In the specimens examined the asci had disappeared. 
Sporidia navicular-fusoid, (subhyaline) pale smoky-brown, ends 
subacute, 10—12 x about 3 micr. 
Hypoxylon ixvestiens, Schw. Syn, N. Am. 1210.—On rotten 
wood, Carolina and Penna. (Schw.), Alabama (Beaumont in Rav.

Seated on a thick sterile crust that spreads over and blackens the 
wood following all the inequalities of its surface. On this, crust 
stand denselv crowded in a single series the regularly oblong 
perithecia forming a continuous layer about J mm. thick and 4—9 
cm. long and wide. The stroma is very scanty covering the per¬ 
ithecia with a thin black stratum maitnnillose above from the 
slightly projecting perithecia, with their papilliform deciduous 
ostiola. In the specimens in Rav. Car. as well as in the La. 
specc. the surface of the stroma has a distinct purplish tinge. We 
have not seen the asci but the sporidia are oblong, pale brown 
6—10 (mostly 6—8) x 3—4. H. effusum Nitschke is closely 
allied to this. 
Hypoxylon Ravenelti, Rehm. Hedwigia, 1882, p. 137.— (H. 
confluens, Fr. in Rav, F. Am. 348.) On bark of decaying oak, 
Darien, Ga. Perithecia single or concrescent 2—8 together, 
occasionally seriate 6—12 in a series 3—J3 mm. long, nearly glo¬ 
bose J—1 mm. diam/ with their bases slightly sunk in the wood 
(our spec, is on wood and not on bark), ostiolum distinct papilli¬ 
form, black and shining. The perithecia are of a dead grayish- 
black. Asci very long, cylindrical with abundant well developed 
•paraphyses. Sporidia elliptical, obtuse, pale-brown, with 1—2 
large nuclei, uniseriate, 10 x 5 micr. 
This is entirely different from H. Ravenelii, Sacc. Syll. I, p. 389
