THE WEST VIRGINIA FLORA

D. (Chorostate) obscura (Peck) Sacc. On Rubus villosns, Feb. 13, 1893 (Nuttall, 1313, 260). D. (Euporthe) aculeata (Schw.) Sacc. On Phytolacca decandra, Nov. 14, 1894. Asci 40 to 55 x 6 to 7.5 ц. Spores 12.5 to 18 x 3 to 3.5 ц (Nuttall, 1754, 639)D. (Tetrastaga) rostellata (Fr.) Nits. On Rubus odoratus, May 31, 1894 (Nuttall, 1528, 560). » AMPHISPHAERIA Ces. & DeNot. A. pinicola Rehm. On Pinus rigida at Glade Creek, and on Pinus Virginiana. May 4, 1894. Spores very variable + 35 x 12 ц (Nuttall, 1499, 480). VALSARIA Ces. & DeNot. V. exasperans (Ger.) Sacc. On Juglans cinerea, Nov. 3, 1893 (Nuttall, 1260, 202). On same, Monongalia, near Morgantown (Sheldon). MASSARIA DeNot. M. Magnoliae E. & E., Field Mus. Bot., 1:141 (1896). Type habitat: On bark of dead limbs Magnolia acu minata, April 25, 1895 (Nuttall, discov. 1818, 700, 705). Perithecia scattered, buried in the bark, depressed-globose. .75 to 1.25 mm. diameter, the subcorneal ostiolum piercing but not perceptibly raising the bark. Asci broad oblong, p. sp. 150 to 200 x 55 to 65 /и. with a very short, nodular stipe, 8-spored, paraphysate. Sporidia crowded-biseriate, oblong or clavate-oblong, 3 to 5-septate, mostly 3-septate, when young, hyaline at first, finally deep brown and then with only one distinct septum, though often 1 to 4 other faint septa can be seen. There is a distinct constriction at the main septum, which is a little below the middle of the spore, but none at the other faint septa which are often wanting. The sporidia measure 65 to 80 x 20 to 25 /1, larger than in M. foedans (Tode), which has sporidia about 50 x 20 ц, 3septate and constricted at all the septa, besides being more distinctly narrowed below. LEPTOSPHAERIA (Pers.) DeNot. L. DoLioLuM (Pers.) DeNot. On Polymnia Uvedalia and Helianthus decapetalus, Nov. 16, 1894. Perithecia covered by outer bark. Asci, fertile part 110x6/1, stipitate, spores overlapping at ends. Spores 22 x 4 /1, 23 x 4.5 ¡i. 25 x 5 ii. 27 x 5 n, 30 x 5 ц; 3-septate,
