THE WEST VIRGINIA FLORA SPHAERIACEAE.

ANTHOSTOMA Nitschke. A. disciNcoLA (Schw.) Sacc. On Crabapple, Monongalia: Morgantown (Sheldon). VALSA Fries. V. CERATOPHORA Tul. On fire killed Hicoria minima, Oct. 17, 1894. On Acer saccharinum, L. Asci 38 x 5 /1, spores 7.5 to 10 x 1.5 to 1.75 1). (Nuttall, 171 1). V. DiospYRi E. & E. Proc. Phil., Acad., 340 (1894). Type habitat : On dead limbs Diospyros Virginiana, Dec. 10, 1893 (Nuttall, discov. 1308, 253). Stroma consisting of the slightly blackened substance of the bark, convex, about 2 mm. diameter, not circumscribed. Perithecia 4 to 10 in a stroma, subglobose, .25 to .33 mm. diameter, necks converging and united above in a small, black disk which perforates the pustuli form-elevated epider mis, but does not rise above it. Ostiola short, conic-cylin drical, with a smooth, round opening crowded and finally obliterating the disk. Asci clavate-lanceolate, p. sp. 25 x 5 /1, 8-spored, paraphysate. Sporidia allantoid, hyaline, 8 to 10 x 1.5 to 2 ц. Spermogonia (Cytispora), stroma multilocular gray inside, opening by a single, central pore. Spermatia allantoid, hyaline, moderately curved, 4 to 5 x 1.25 ц. V. etHERiALis E. & E. Proc. Phila. Acad., 341 (1894). Type habitat : On dead limbs of Acer rubrum, Feb., 1894 (Nuttall, discov. 1304, 373). Stromata cortical, thickly scattered, convex 1 to 1.5 mm. diameter. Perithecia 6 to 12 together, circinate, buried in the unaltered substance of the bark, small, 150 to 250 д diameter their short necks terminating in an erumpent, com pact fascicle of obtuse, black, slightly umbilicate ostiola closely embraced by the epidermis and scarcely rising above it. Asci (p. sp.) fusoid, 15 to 22 x 4 to 4.5 д, stipitate, 8spored. Spordia biseriate, allantoid, hyaline, curved, slender, 5 to 6 x about i ц. When well developed, the epidermis is raised into subdiscoid pustules in which the slight protub erances indicate the position of the subjacent perithecia. V. delicatula C. & E. has fewer, larger perithecia and broader sporidia. V. mierosbora Cke. & Plowr. has also larger perithecia and yellowish sporidia, and the ostiola are more or less distinctly sulcate, indicating its close relation ship to Eutypella. In V. etherialis the spordia both in and out of the asci are perfectly hyaline.
