8-spored, Avith filiform paraphyses. Sporidia subbiseriate, cylin- 

 drical, nearly straight, multi-nucleate, hyaline, 30-60x3/;.. 



Coryne ellidl Berk, Stilbum magnum Pk., is probably the conidial 

 stage. 

 Niptera lithospermi E. & E. 



On dead stems of Lithospennum canescens, Mount Helena, Mon- 

 tana. Oct., 1889. (Anderson & Kelsey, No. 4.) 



Erumpent-superficial, scattered, sessile, about t mm. diam., closed 

 at first and opening tardily, black-brown outside and granular from 

 the projecting cells of the external layer, margin whitish. Disk 

 livid white becoming darker, cup-shaped. Asci oblong-cylindrical, 

 sessile, 45-55 x 8-10//, with obscure paraphyses. Sporidia biseriate, 

 oblong-cylindrical, 1 -septate and mostly broadly constricted in the 

 middle, hyaline, 12-20 (mostly 12-15) x 3-3?//. ends, rounded or 

 sometimes obtusely pointed. Hardly distinguishable from Pyreno- 

 peziza nigrella Fckl. outwardly, but the sporidia are very different. 



Mollisia trametis E. & E. 



Parasitic on Polyjjorus stevensii Berk. On a decaying oak chip, 

 Newfield, N. J. Dec, 1888. 



Growing on the margin and inner surface of the pores. Cups 

 obconic, 114-150// diam. honey colored, of fibrous structure, the 

 ends of the fibers projecting so that the outer surface and the mar- 

 gin appear granulose-pubescent or as if covered with sharp pointed 

 granules, convex-hemispherical at first and immarginate, so as to 

 resemble Nedria, but soon becoming concave with a distinct sub- 

 fimbriate margin. Asci clavate-oblong, 20-23x4-5//, sessile and 

 without paraphyses. Sporidia biseriate or obliquely uniseriate, nar- 

 row-elliptical or clavate oblong, hyaline, continuous, 3*-4j x H-2//. 

 The cups are so near the color of the pores of the fungus on which 

 they grow as to be easily overlooked. 

 Mollisia nipteroides E. & E. 



On dead stems of Smilax, St. Martinville, La. March, 1889. 

 (Langlois, No. 1,674.) 



Shallow cup-shaped, 1-1 5 mm., across contracted below into a 

 very short stem (almost sessile). Umber color but whitened outside 

 by a pruinose coat and a short erect glandular pubescence which is 

 more abundant toward the margin. Asci oblong-cylindrical, 35-40 

 x 5-6//, sessile. Paraphyses branched above and bearing minute 

 globose conidia. Sporidia biseriate, hyaline, 2-3-nucleate, oblong,
