[VOL. IV, NO. 9> 
papillate from the slightly prominent perithecia which are of 
medium size and are closely packed in 'a single layer. Asci 
cylindrical, 50—'60 (p. sp.) long 7—8 micr. broad. Sporidia 
obliquely monostichous, ovate, sub-acute at each end and slightly 
inequilateral, opake, 10—14 x 5—6. 
Hypoxylon piceum, Ellis, Am. Nat. Feb. 1883, p. 194.—On 
rotten wood, Iowa, (Holway). Stroma effused, subelliptical or 
elongated, often b}^ confluence forming patches 4—8 cm. long by 
half as wide, dark brown, nearly black within, surface wrinkled 
and covered with a dull yellow conidial growth which also spreads 
over the surface of the wood adjacent and consists of short, rudi¬ 
mentary, irregularly branched hyphae covered with the minute, 
dust like conidia. Perithecia in 2—3 layers densely crowded and 
angular by compression, the lower layer much elongated. Ostiola 
minute, scarcely visible. Asci? Sporidia navicular, brown, 11— 
12x4. The stromata resemble blotches of black pitch dusted 
over with yellow meal and are of about the consistency of beeswax. 
Hypoxylon fuscopurpureum. Schw. Syn. N. Am. 1209—On 
rotten wood and bark, Carolina and Penna. (Schweinitz). Va¬ 
riously effused, margin generally sterile. Outer crust rather hard, 
black and shining within, surface elegantly purple, at length dark- 
purple, regularly granulose from the subjacent perithecia which 
are oblong ovate, polystichous, numerous, small, immersed in 
the shining black stroma, staining the [wood or bark around it 
black, inseparably adnate, extending for an inch or more in 
length and preferring depressions in the surface of the wood. 
Sec. Cooke, 1. c. the sporidia are 14—7 micr. The specimen 
in Rav. F. Am. 653 on bark of ash, seaboard of So. Ca. has 
sporidia 9—11 x 4|—6 and looks more like a smooth form 
of H 7'ubiginosum ,

Hypoxylon florideum , B. & C, Grev. IV, p. 50.— On Acer 
rubrum, Carolina (Ravenel). Effused, for many inches, undulate, 
wine colored, pulverulent, perithecia hidden. Sporidia cymbiform, 
uninucleate, 9—10 x 3J, Asci linear. 
Hypoxylon jecorinum , B. & Rav. Grev. IV. p. 50.—Effused, 
an inch or more long and broad, at first covered with a tawny 
yellow powder then liver colored, dotted with the dark ostiola. 
Sporidia sec. Cooke 1, c. 9x4 micr. The specimens in Rav. 
Fungi Car. IV, 37, have the stroma subelliptical, 1—2x 1 cm. 
and sporidia 7—8 x 3—4. Florida specimens collected by Col. 
Calkins during the winter of 1887, have the stroma 1J—3 x 2— 
21 cm. Ravenels specimens are on bark of Acer rubrum and the 
Florida specimens are also on bark of some deciduous tree. The
