or oblong, 1-2| x |-| nun. black, not striate; lips incurved, nearly 

 closed at first, becoming finally more or less open so as often to expose 

 the narrow-lanceolate, black or slate-coloi^ed disk, generally more or 

 less distinctly transversely wrinkled. Asci clavate-oblong, short-stipi- 

 tate, 100-115x30-35 [i (p. sp.), paraphysate, 8-spored. Sporidia 

 biseriate, broad-fiisoid, uniseptate and constricted in the middle, then 

 multi- (12-15-) septate, and muriform, olive-brown, slightly curved, 

 50-60x10-12//. 



On dead limbs of Salix lasiolepis and Ceanothus, California 

 (Harkness). 



The asci and sporidia do not differ from those of H. vulvatum, 

 Schw., unless the sporidia may be a little narrower, but the perithecia 

 are more open and not striate. H. Geanothi, Phil. & Hark. (sec. 

 specc. from Harkness) does not differ in any way from H. prominens. 

 Both are erumpent-superficial, with the disk finally more or less 

 exposed, and the asci and sporidia are the same. Probal)ly both 

 should be considered mere varr. of ^. vulvatum, Schw. 



H. stygium, (Cke.)

 Hysterograpkium siygium, Sacc. Syll, 5775, 



Superficial, scattered. Perithecia lanceolate, black, shining, 

 smooth, |-1 mm. long. Asci clavate. Sporidia elliptical or ovate, 

 multiseptate-muriform, dark brown, 30 x 13 fi.

 Grevillea.

Perithecia gregarious, seated on the dark-colored, decorticated 

 surface of the wood, oblong or oblong elliptical, straight, seldom some- 

 what curved,, obtuse, prominent, mostly smooth, deeply cleft; lips 

 nearly closed, black, carbonaceous, 2-4x1 mm. Asci clavate, thick- 

 walled, 120-150x25 //, 8-spored, with paraphyses branched above 

 and forming a thick, brown layer (epithecium) above the asci. Spo- 

 ridia biseriate, oblong-elliptical, obtuse, seldom somewhat constricted 

 in the middle, hyaline, becoming brown, 9-11-septate, with a longi- 

 tudinal septum, 36-40 x 12-15 /i. 



On wood, Carolina and Pennsylvania (Schw.). 



The specc. of this species in .Herb. Schw. are without fruit. The 

 diagnosis is from Rehm (in Die Pilze).
