NEW SPECIES OF FVNGI. 21 



brown hairs, the uppermost .01 to .014 in. long, .0003 broad, the 



disk whitish, concealed in the dry plant by the hairs of the margin ; 



asci cylindrical, .0025 to .003 in. long, .00025 to .0003 broad : spores 



oblong or subfusiform, straight or slightly curved, colorless, .0003 to 



.0004 in. long, .00008 to .00012 broad. 



Dead stems of Ewpatorium maculatum. Adirondack mountains. 



Jury- 

 Apparently near P. relicina Fr., but that is described as sessile 



and of a bay color. 



This and the next following species belong to the subgenus

Pezlza urticina. 



Eeceptacle minute, .007 to .014in. broad, sessile, subglobose, almost 

 hyaline, and with the mouth connivent when moist, whitish and pul- 

 veruleut-hairy when dry ; asci subfusiform ; spores crowded or bise- 

 riate, fusiform, .0004 to .0005 in. long ; paraphyses filiform. 



Dead stems of nettles, Laportea Canadensis. Catskill mountains. 

 July. 



When moist the hairs are appressed and the cups appear longitud-

 plants are so small that they appear to the naked eye like minute 

 white grains. 



Helotium fraternum. 



Plate 1, figs. 12-14. 



Eeceptacle small, \ to 1 line broad, stipitate, the disk plane 

 or slightly concave, pallid or reddish-yellow, becoming more con- 

 cave and dull-red in drying, the stem about equal in length to the 

 diameter of the receptacle ; asci clavate or subcylindrical, .003 to 

 .004 in. long, .0004 to .0005 broad ; spores crowded or biseriate, 

 subcylindrical, .00065 to .0008 in. long, .00016 to .0002 broad ; para- 

 physes numerous, filiform, scarcely thickened at the tips. 



Petioles and midveins of fallen leaves of maple, Acer saccharinum.

Pezicula minuta. 



Receptacle minute, .009 to .017 in. broad, numerous, scattered or 

 two or three crowded together, attached to the matrix by a minute
