1897.] Botany. 427 
stout, 2-4 mm. long, substriate, gradually enlarged above, same color 
as the disk. Asci narrow, linear, straight, short-stipitate, 60-65 x 4%, 
paraphysate, 8-spored. Sporidia sub-biseriate, oblong, hyaline, continu- 
ous, 6-8 x 1łx. 
Differs from P. epigaea Karst. in its larger ascoma and much smaller 
sporidia. 
TRICHOPEZIZA COARCTATA E. & E. On dead branches of Vaccinium 
myrtilloides, Mountains, Skamania Co., Wash., July, 1894 (Suksdorf, 
No. 507). 
Scattered, superficial, sessile, hemispheric cup-shaped, smoky-white, 
300-400 diam., thin membranaceous, margin contracted quite strongly 
at first, so as to leave only a small, round opening, and fringed with 
short, fasciculate, smooth hairs about 25 or 30x 2-23y. Asci clavate- 
oblong, 30-35 x 5-6». Sporidia biseriate, ovate, hyaline, 2—nucleate, 
4-5} x 23-3p. 
Closely allied to T. confusa Sacce. (T. punctiformis Rehm.), but dif- 
fers in its longer asci and different character of the hairs. 
ScLERODERRIS ABIETINA E. & E. On bleached bark of fir trees, 
Newfoundland, September, 1896 (Waghorne, No. 61). 
Erumpent-superficial, black, obconical, about } mm. diam., hymen- 
ium discoid or convex, areolate, with a very narrow, thin, almost obso- 
lete margin. Asci clavate-oblong, sessile, rounded above, 70 x 15y, 
8-spored, overtopped by the filiform paraphyses. Sporidia fasciculate, 
clavate-cylindrical, multinucleate, becoming multiseptate, 50-65 x 3-44, 
hyaline. 
HOLWAYA TILIACEA E. & E. On bark of dead Tilia, Canada 
(Macoun). 
Ascomata gregarious or solitary, subcupulate, expanding to plane, 
thin (when dry), margin subundulate, 2-4 mm. across, black, with a 
short, thick stipe. Asci cylindrical, short-stipitate, 120-150 x 7-8. 
Paraphyses? Sporidia fasciculate or subbiseriate, narrow fusoid-cylin- 
drical, nearly straight, multinucleate, hyaline, 40-62 x 3-33 n. 
Closely resembles outwardly Bulgaria inquinans. Coryne ellisii 
Berk. (Stilbum magnum Pk.) is found with this, and may be its conid- 
ial stage. 
Uromyces rosicota E. & E. On leaves of Rosa fendleri? Craw- 
ford, Nebraska, June, 1896 (Rev. J. M. Bates, No. 438). 
III. Sori hypophyllous, chestnut-brown, confluent over the entire 
lower face of the leaves, at first covered by the epidermis, soon naked. 
Spores globose or obovate, 20-35» in the longer diam., epispore thick 
and coarsely tuberculose. Pedicels stout, about as long as the spores.
