Ellis and Everhart : New Species of Fungi 51 



Erumpent, mostly cespitose and connate, forming tufts 0.5-1 

 cm. in diameter, obconic, discoid, concave above at first but when 

 mature convex above, variously wrinkled, folded and immarginate, 

 liver-color with a lilac tint when fresh, drab-color when dry and 

 quite fragile, texture of coarse inflated hyphae resembling, when 

 the dry plant is broken open, a mass of dirty light-yellowish to- 

 mentum : basidia clavate-cylindrical, 40-50 x 6-7 [i with two 

 short, obtuse sterigmata : spores shaped like apple seeds, 12-20 

 (mostly 1 5) x 6-8 //, filled with minute nuclei, becoming 3 or 

 more septate, hyaline. 



When dry, bears a striking resemblance to a cespitose Cenan- 

 giiim. Tremella sarcoides (Dicks.) is found with this. 



Asterina Mexicana E. & E. 



On Agave Mexicana, City of Mexico, May, 1898 (Dr. B. F. G. 

 Egeling). 



Perithecia amphigenous, subastomous, small ( r 1 0-1 50 //), 

 rough, black, fringed around the base with coarse, brown, subin- 

 curved hairs, seated on appressed, reticuktely branched, black 

 mycelium of the Meliola type : asci obovate, abruptly short-stipi- 

 tate, 40— 6ox 20— 30/i, or becoming subglobose, 8-spored : sporidia 

 crowded, clavate-cylindrical, uniseptate and constricted near the 

 upper end, upper cell globose, and easily separable, lower cell ob- 

 long, 22-27 X 8-1 o/i, filled with granular matter, nearly hyaline, 

 becoming brown. 



The perithecia are crowded in orbicular patches about 1 cm. 

 diam., oftea with a white spot in the center. 



Melanomma gregarium E. & E. 



On decorticated cottonwood limbs, Rooks Co., Kansas, Jan. 



1899 (Bartholomew, no. 2532). 



Perithecia gregarious, globose-conical, slate color and minutely 

 roughened, 250-350 <i in diameter, base slightly sunk in the wood, 

 finally collapsing above : ostiolum papilliform, black and shining : 

 asci clavate-cylindrical, p. sp. 50-70 x IO-I2/I with abundant, 

 filiform paraphyses : sporidia subbiseriate, oblong or ovate -ellipti- 

 cal, 3-septate and finally slightly constricted at the septa, 12-15 x 



5-7 ,"• 



Diners from M. rhypodes E. & E. in its broader, shorter 

 sporidia and collapsing perithecia.
