52 THIRTIETH REPORT ON THE STATE MUSEUM. 
The perithecia are epiphyllous, the spores are obovate or sub- 
angular and are involved in mucus. The brownish spots fre- 
quently have a darker border. 
SPHAZROPSIS SYRINGE P. & C. n. sp. 
Perithecia small, scattered, erumpent, black ; spores oblong 
or elliptical, colored, .0008—.001’ long, .0004 broad. 
Dead lilac twigs. Buffalo. January. Clinton. 
Perhaps this is only a form of Diplodia Syringe Awd. 
DiPLopia THUJINA P. & C. 
Perithecia subhemispherical or elliptical, rugulose or sub- 
striate, black; spores oblong-elliptical, slightly constricted, 
colored, .0007—.0009' long. 
Wood and bark of Thuja occidentalis. Buffalo. May. 
Clinton. . 
The form on bark has the perithecia erumpent and closely 
surrounded by the epidermis. In the other the perithecia are 
nearly free and often elliptical in shape. 
ACROSPERMUM GRAMINUM ZLib. 
Dead stems of grass, Calamagrostis Canadensis. West 
Albany. June. 
EXCIPULA LANUGINOSA n. sp. (Plate I, figs..14-18.) 
Perithecia small, yellowish or orange, numerous, almost con- 
cealed by the long, soft, wooly, dingy-white or pinkish-white 
hairs ; spores oblong, colorless, .0003—.00035' long. 
Dead stems of melilot. Bethlehem. September. 
The species is remarkable for its long, pale, wooly hairs 
and its light-colored perithecia. These are sometimes so 
crowded together that they appear to form a continuous fleecy 
stratum. A relationship with the genus Trichoderma is 
indicated. 
DISCELLA CANADENSIS 7. Sp. 
Pustules very small, perithecia obsolete or wholly wanting ; 
spores oozing out in a black mass or in tendrils, oblong or 
oblong-ovate, .0008—.001' long, at first pale, then colored, some 
of them becoming uniseptate. 
Dead branches of Amelanchier Canadensis. Center. June. 
The subequal hyaline sporophores sometimes remain attached 
to the young spores. The species approaches the genus 
Melanconium.
