NEW WEST AMERICAN EUNGL 



By J. B. Eiiiiis AND B. M. Everhart. 



Helanopsamma Kansensis, E. & E. 



On bark of living trees of Ulmus Americana^ Eoclvport, 

 Kansas, Sept., 1893, Bartholomew, 1139. 



Perithecia gregarious or scattered, superficial, hemisplieri- 

 cal, brownish-black, \ — | mm. diam., with a minute but dis- 

 tinct black papilliform ostiolum. Asci cylindrical, 100 — 

 110x10 — 12yW, paraphysate, 8-spored, short-stipitate. Spo- 

 ridia biseriate above, overlapping below, broad - f usoid, 

 hyaline, uniseptate and constricted at the septum, each of the 

 cells slightly constricted near the middle, but, as far as 

 seen, not visibly septate, 18 — 22x6 — %}x ends acute at first, 

 finally obtuse. 



Comes near M. ahscondita^ E. & E., but there is no black, 

 crustaceous subiculum, and the sporidia are more attenu- 

 ated toward the ends with the cells constricted. 



3Ielaiiomma rhypodes, E. & E. 



On outer bark of living Cottonwood trees, Rockport, Kan- 

 sas, Aug., 1893. Bartholomew, No. 1073. 



Erumpent-superficial, conic-hemispherical, with the flat- 

 tened base slightly sunk in the bark, about | mm. diam., 

 rough and grayish or yellowish pruinose. Ostiolum obtusely 

 conical, soon with a large opening. Asci clavate-cylindrical, 

 80— 100x12— 15/i (p. sp. 75— 80>u long), with abundant par- 

 aphyses more or less branched and enlarged at the tips, 

 8-spored. Sporidia biseriate above, fusoid-oblong, slightly 

 curved, mostly a little narrower below, at first hyaline and 

 uniseptate, becoming olive-brown and 3-septate, constricted 

 at the middle septum, with the next to the upper cell mostly 



a little swollen, each cell 1— 2-nucleate, 19—22x7—8//, ends 

 obtuse. 



Differs from M. inspissa, Scliw., and M. decidtia.^E.&K, 



in its pruinose perithecia not collapsing and its broader 

 sporidia. 



Erythea, Vol. II, No. 2, (9 Feb., 1894).
