FUNGI. 



TRYBLIDIACE^E. 



HETEROSPHAERIA FENDLERAECOLA, n. sp. Ascocarps 

 thickly scattered, at first buried, becoming erumpent or 

 subfree, closely sessile, dark brown, almost black, coriaceous, 

 cup shaped, about J-lmm., the epithecium at first covered 

 by a membrane that soon splits stellately into about 20 

 marginal teeth that are erect, exposing the epithecium when 

 moist but closed down over it when dry; epithecium dark 

 brown; asci 50-60x5/u., cylindric-clavate, embedded in the 

 numerous paraphyses that unite above in a well marked 

 epithecium; ascospores distichous or inordinate, spindle 

 shaped, hyaline, somewhat unequally uniseptate, 8-10x2-3/i. 



On dead weather-worn twigs of Fendlera rupicola, Her- 

 mosa, Colo., April 4, (no number given. E. L. G.). 



TRYBLIDIOPSIS OCCIDENTALIS, n. sp. Ascocarps scattered, 

 at first buried, then prominently emergent and almost free, 

 sessile, black, dull, somewhat rugose, long closed, at length 

 irregularly or stellately dehiscent exposing the dark brown 

 disc, from -lmm. in diameter; asci broadly oval, thick 

 walled, about 100x25-30/*; paraphyses greenish, much ex- 

 ceeding the asci, branched and interwoven above into a 

 dense epithecium; tips scarcely swollen; ascospores broadly 

 oval, ends rounded, uniseptate, at first hyaline and sur- 

 rounded by a gelatinous envelope that is thickest at the 

 septum, finally loosing this coating and becoming dark 

 brown and somewhat constricted, about 30xl8/x. 



On the smooth bark of dead twigs of Jwiiperus, Hermosa, 

 Colo., April 3. This is the first species of this well marked 

 genus to be detected in this country. 



TRYBLIDIUM OCCIDENTALS, n. sp. Gregarious, often 

 crowded; ascocarps Patellaria-like, at first somewhat sunken 

 in the matrix, then free, black, subrugose, about ^mm.
