WEST VIRGINIA GEOLOGICAL SURVEY 45 ILLOSPORIUM Mart I. CAESPITOSUM E. & E., Proc. Phila. Acad., 1894, 385. TYPE HABITAT: On rotten log, Nov. 15, 1893 (Nuttall, discov. 1286, 231). Sporodochia globose, 100 to 110 H diameter, cespitose, forming tufts about I mm, diameter. Hyphæ 6 to 8 y thick, branched, the branches curved or tortuous. Conidia globose or ovate 6 to 12 # diameter. Differs from I coccinellum Cke. in its color, and larger cespitose sporodochia. I. MALIFOLIORUM, J. L. Sheldon, Torreya, 8:139-41 (1908). Spots suborbicular, or coalescing and becoming irregular, brown or sometimes mottled with gray and with a small gray spot near the center, 5 to 15 mm. in diameter; sporodochia hypophyllous, minute, gelatinous, yellowish-amher and blackening, subspherical when moist (150u), becoming disc-shaped or irregular when dry (60 to 100g) ; sporophores branched; conidia hyaline, oblong, I x 3.5 to 4pl. On leaves of Malus in various parts of the State (Sheldon). Greenbrier, near White Sulphur Springs (Waite). erichute, gelatin5 mm. iny and wit HYMENULA Fr. H. CEREALIS E. & E., Proc. Phila. Acad., 1894, 386. TYPE HABITAT: On wheat straw Triticum sp. brought in from Painesville, Ohio, May 24, 1894 (Nuttall, discov. 1520, 495). Sporodochia gelatinous, orbicular, yellowish-aniber color becoming darker, at first sub-pulvinate, becoming depressed or flattened, .5 to 75 mm, diameter. Basidia slender, 25 to 30 x 1.25 # simple or oftener branched. The branches erect. Conidia hyaline, oblong, minute, 3 to 4x I to 1.25 t. CYLINDROCOLLA, Bon. C. DENDROCTONI Peck, in Millsp. Flora, W. Va., 1892, 516. TYPE HABITAT: On dead insects, Dendroctonus frontalis, beneath the bark of pine. Hampshire Co., near Romney, (Müllspaugh). The insects are probably killed by this fungus, as they lie dead in their burrows in the inner bark of the tree (Pinus Virginiana). Sporodochia minute, forming irregular masses, soft, somewhat waxy, white or whitish; sporophores slender, abundantly branched above, often compacted below into a short stem-like base, spores catenulate, short cylindrical, subtruncate, colorless, .00016 to .0002 in. long, .00008 to .0001 in. broad.
