The stem arises from a narrow, cup-shaped, black sclerotium, 

 the origin of which I have not yet been able to determine. The 

 sclerotium is of the same shape as that which originates in the 

 petals of Magnolia and produces Peziza gracilipes, Cke., but is larger 

 (i-4th inch across) and lies loose among mosses. The Peziza itself 

 much resembles the last-named species, but is distinguished there- 

 from by its shorter, thicker stem, its larger size throughout, and -its 

 tetrasporous asci.

Patellaria clavata.— Scattered, sessile, patelliform ; disk

Patellaria imperfecta-.— Minute, .015' diam., orbicular, ses-

Patellaria tuberculosa .--Scattered, sessile, turbinate, .02 

 diameter, soft, tuberculose, dirty-white, externally darker, substriate

 ,ooo55'x.ooo6'; paraphyses rather stout, simple or branched, thicken- 

 ed above; sporidia biseriate, oblong-elliptic, 3-septate, .ooo8'~.oooo 

 X.00025 . 



In the fresh state the disk is swollen so as to conceal the margin 

 and outer surface, and the whole resembles a globule of transparent 

 gelatine; but, when dry, the dark exterior closes over the contracted 

 disk so that the latter appears nearly black.
