On dead herbaceous stems. (No. 66.) 



Pkziza (Dasyscypha) crossota.— Sessile, greenish, spherical at 

 first and with a narrow opening, expanding to concave, margin 

 thickly fringed with greenish, straight, 4-6-septate, obtuse hairs, about 

 .003 long by .0003' thick; disk livid when fresh, pale greenish when 

 dry ; asci cylmdrical, abruptly narrowed below into a short stipe ; 

 paraphyses Imear, faintly septate, stout, not thickened above ; spo- 

 ridia reniform-oblong, hyaline, continuous, .0003'-. ooo35'x.oooi25'. 



On weather-beaten wood with No. 73. May.» 



This and the two foregoing species are closely allied, but are 

 easily distinguished by the characters given. 



Peziza (Tapesia) EARiNA.— Thin and soft, seated on a loose 

 mycelium of dirty- white, matted, cottony hairs, orbicular, about one 

 line broad, fibrous^ in texture ; disk brick-red when dry ; asci cylin- 

 drical, .005 X.0005' ; paraphyses rather stout, thickened above ; spo- 



ridia unisenate, elliptical, hyaline (mostly with ■ a nucleus,) about 

 .0006 x,ooo3 . 



On dead stems and leaves of grasses and on weather-beaten wood 

 still partly covered with snow. April and May. (No. 67.) 



Propolis sphaerelloides.— Erumpent, orbicular, .008-0085' in 

 diameter, scarcely prominent when dry, but swelling out in little 

 tubercles when moist and exposing a pale, flesh-colored disk sur- 

 rounded by a subfimbnate, dark brown margin ; asci clavate-cylin- 

 drical, .0018 -.oo23'x.ooo3'- 0004'; paraphyses stout and mostly 

 thickened above ; sporidia biseriate, oblong or clavate-oblong, 2-4- 

 nucleate and finally uniseptate, .ooo5'x.oooi25'- 00015' 



Sometimes several individuals, ranged side by side, form an ir- 

 regular ring around the stem of the /uncus on which the species is 

 parasitic. Looks much like a Sp/merel!^\\\\tn dry (No 70 ) 



ACROSPERMUM CORRUGATUM.-Liguliform, black, erect, .065'- 

 07 high and .02 wide, surrounded at the base by a mycelium of 

 brown, matted hairs, strongly transversely striate on both sides, 

 compressed and truncate above so that the apex is in shape like the 

 edge of a chisel; asci linear, long and narrow, .oi8'-.o2'x.ooo4' ; 

 paraphyses filiform, abundant, endochrome many-parted; sporidia 

 linear, nearly as long as the asci, separating into cylindrical, vsep- 

 tate joints, .0007 -.0008' long. ^ o t- 



On weather-beaten wood. (No. 73.) 



DOTHIDEA TUBERCULiFORMis.— Stroma disciform, contracted be- 

 low into a thick, narrow base, submarginate above, .ooV-.qga' in 

 diameter, of coarse, cellular structure, ascigerous cavities nLute • 

 asci oblong-cylmdrical, .0013 x.ooo6' ; sporidia biseriate, subhyaline 

 granular, uniseptate, .0006 -.ooo7'x.oooi75', septum mostly nearer one 



On bark of dead twigs of some unknown tree or shrub (No 68 ^ 

 Leptosphaeria TENERA.-Gregarious, seated just beneath the 

 cuticle, which IS blackened by the mycelium of dark, sparingly sep- 

 tate, branching breads ; asci narrowly clavate, .oo3'x.c?o2'-"ooo2 5'- 

 paraphyses nucleate; sporidia overlapping and crowded above' 

 fusiform s-septate, yellowish, slightly constricted at the septa and 

 the next to the upper division slightly swollen, mostly straight
