By J. B. Ellis. 



Pe2iza (Dasyscyphae) campanula. — Pulvinate, sessile, a little 

 more than one line high, and, when open, about one line broad, cov- 

 ered with a dense coat of fine, snow-white, crisped hairs; disk light 

 rufous or flesh-color, bell-shaped, contracted when dry and concealed 

 by the dense fringe of hairs; asci sessile, .ooi'x.0002'; paraphyses(?); 

 sporidia biseriate, oblong, obliquely apiculate at one end, hyaline, 

 .ooo3'x.oooo65'. Substance of the cup thin and of a fibrous texture. 



A most beautiful species. When fresh, the bell-shaped or short-cyl- 

 indric cavity of the disk gives it the aspect of Solenia. 



On quaking ash, Pleasant Valley, Utah. S. J. Harkness. 



Peziza (Tapesia) prolific a. — Gregarious, sessile, minute, densely 

 clothed with septate, coarse, spreading, cinereous hairs; disk cup- 

 shaped, dark, margin entire ; asci clavate, spore-bearing part about 

 .001' lonp;; sporidia biseriate, cylindrical, curved, obtuse, nearly hya- 

 line, .ooo3'-ooo35'x.oooi^ 



The hairs appear brownish under the microscope, but ash-colored 

 to the naked eye. 



On the end of a piece of oak firewood. December. 



Peziza nyssaegena. — Stipitate,.brown, concave, i-4th inch, or a 

 little less, across, margin paler, obtuse, stipe \ — 2 long, mostly flex- 

 uous, half a line thick; asci cylindric, .oo47'x.ooo35'; paraphyses lin- 

 ear, rather stout, not thickened above; sporidia uniseriate, elliptical, 

 hyaline* .ooo45'x.ooo2'. 



The stem is thicker and stouter than that of P. incondita^ which is 

 also of a paler color. 



On old nutlets of Nyssa inultiflora buried in mud and decaying 

 leaves in swampy ground. September. (Ellis, in N, Am. Fungi, 

 No. 389.) 



Peziza (Hymenoscyphae) simulata. — Gregarious, stipitate ; 

 disk circular, plane or slightly umbilicate, dull watery- white, i-8th 

 inch across, thin, becoming concave in drying. Stipe about i-8th inch 

 high, smooth, slightly contracted and darker below; asci abundant, 

 sessile, cylindrical; paraphyses linear; sporidia elliptical, hyaline, 

 about .0005' long. 



The stipe arises directly from, the leaf, mostly from the veinlets, 

 and is not attached to any sclerotium. When young the whole plant 

 is milk-white- 



On decaying maple-leaves lying on wet ground. June. 



Peziza incondita, — Solitary, stipitate, pale chestnut-color; disk 

 plane or convex i-8th to i-4th inch across, without any distinct mar- 

 gin; stipe central, erect, brownish, about half an inch high, firm; asci 

 cylindrico-clavate, sessile, about -003' long; sporidia 4 in each ascus, 

 elliptical or ovato-elliptical, hyaline, .0004'-. 0005' long by .00025'- 

 .0003' wide.
