NEW SPECIES OF FUNGI. 17 



groups or clusters and forming small protuberances or tubercles on 

 the dry stems. 



Common saltwort, Sah'corma herbacea. Syracuse. September. 



The species is remarkable for the large size of the spores and their 

 clustered mode of growth. 



Periconia albiceps. 



Plate 1, tigs. 8-11. 



Stems short, .02 to .03 in. high, equal or slightly tapering upward, 

 black ; head subglobose, white ; spores oblong or subfusiform, color- 

 less, .0003 to .0006 in. long. 



Dead stems of balmony, Chelone glabra. Sandlake. May. 



The stems of the fungus are composed of compacted filaments, 

 and I have followed the English mycologists in referring the species 

 to the genus Periconia. It is Sporocybe of Bonorden. 



Gonatobotryum tenellum. 



Patches thinly effused, subolivaceous ; flocci subtufted, erect, slen- 

 der, simple or rarely branched, not nodulose-inflated, septate, brown, 

 .006 to .014 in. high; spores in verticels of 2 to 4 at the septa, 

 oblong, simple, subfuliginous, .00045 to .0005 in. long, .00016 to 

 .0002 broad. 



Dead stems of stoneroot, Gollinsonia Canadensis. North Green- 

 bush. October. 



By reason of the equal, not nodulose, flocci the species does not 

 well agree with the character of the genus. Because of the colored 

 flocci it would go no better in Arthrinium. 



Ramularia effusa. 



Hypophyllous, often occupying the whole lower surface of the 

 leaf, whitish ; spores very variable, globose, obovate-elliptical, ob- 

 long or cylindrical, .00016 to .0011 in. long, .00016 to .0002 broad, 

 sometimes uniseptate. 



Living leaves of black huckleberry, Gaylussacia resinosa. Karner. 

 July. 



Sometimes all the leaves on a branch have the lower surface 

 whitened by this fungus. 



Ramularia albomaculata. 



Spots suborbicular, 2 to 3 lines in diameter, sometimes conflu- 

 ent, pale yellowish-green on the upper surface, becoming purplish
