Ellis and Everhart : New Species of Fungi 59 



Hadotrichum lupini E. & E. 



On leaves of Lupinus humilis, Wyoming (Nelson), on L. albi- 



frons, California (McClatchie), on Lupinus sp., Colorado (C. F. 

 Baker). 



Fertile hyphae clavate-cylindrical, continuous, olivaceous, 20- 

 25X4/-*, densely fasciculate: conidia globose, subolivaceous, 

 smooth, with a rather thick epispore, 10-12// in diameter. 



In company with Phyllosticta ferax E. & E. (Proc. Phil. Acad. 

 l8 94: 355). 



Mostly in the center of brownish dead spots surrounded by a 

 broad belt of perithecia of the Phyllosticta of which it seems to be 

 the conidial stage. 



Pilacre pallida E. & E. 



On rotten wood, Chattanooga, Colorado, June 19, 1899 (E. 

 Bethel, no. 489). 



Gregarious. Stipe stout, 1.5-2 mm. high, .75 mm. thick, equal 

 or slightly contracted below, surrounded at base by white, straight, 

 radiating threads which are closely appressed to the matrix, surface 

 of stipe slightly roughened, dirty-flesh-color : head depressed, sub- 

 discoid, subumbilicate beneath, 1-1.5 mm. across, covered with a 

 thin umber colored membrane which soon disappears, exposing the 

 dirty white, coarsely reticulate capillitium, the fertile threads of 

 which are roughened by minute projecting points bearing the ellip- 

 tical 6-8 x 5-6 ju, nearly hyaline conidia. 



The head finally falls off all but the base which remains as a 

 white convex disk on the top of the stipe. 



M 



Exosporium pallidum E. & E. 



On dead limbs of Rhus Toxicodendron, Morrison, Colorado, 

 iy, 1*899 (Prof. E. Bethel, no. 475). 



Sporodochia bursting through the epidermis, 3-4 or more to- 

 gether, stromatically connected at base or occasionally single, 0.5- 

 0, 75 mm - in diameter, mostly flattened above, grayish inside, densely 

 clothed on the surface with the stout (20-30 x 5-7 ft) hyaline 

 (becoming black)? simple sporophores bearing at their tips the 

 oblong or oblong-elliptical, 2- (sometimes 3-) septate more or less 

 constricted, yellow-brown conidia 25-50 x 14-18 /*. 



differs from E. clavuligcrum Lk. in its continuous, hyaline 

 porophores.
