Coprinus confertus Copeland. Gregarious and caespitose, varying 

 greatly with the weather; pileus fleshy, conical; if grown in dry weather 

 very thick, covered with appressed, whitish, cottony flakes, the margin 

 entire or cleft a few times; hut when rainy thinner, clothed with an 

 evanescent, silky net, grayish-black, striate, with tawny or stramineous

 but close; spores ovate, 14 to 16 by 7.5 to 9 /x truncate, black; stipe 

 white, smooth, hollow, in dry weather turbinate, 2.5 cm. high, 1.5 cm. 

 thick; but Avhen rainy, as much as 10 cm. high, G to 15 mm. thick, equal, 

 or narrowing upward, base equal or subbulbose, with a strong radical cord. 



Manila, on horse manure. 



This species is near C. picaceus Fries, differing from it chiefly in the 

 strongly rooting base and in growing on manure instead of on ground. 



C. ater Copeland. Odorless, with fairly agreeable taste; pileus obtusely 

 conical at first, becoming plane, 14 mm. broad, disk tawny, periphery 

 passing from dark gray to very black, bearing minute, deciduous, dark 

 brown scales or granules, the flesh .30 /j, thick; gills free, narrow, black; 

 spores black, 15 by /x, exstipitate; stipe fistulose, smooth, white, equal, 

 or narrowed upward, at most 5 cm. high, 1.5 mm. thick, most often 2.5 

 cm. high, 0.8 mm. thick. 



Davao, on horse manure. 



C. ornatus Copeland. Odorless, with fair flavor; pileus passing from 

 canipanulate to broadly conical, obtuse, 12 mm. wide, sulcate, the disk 

 tawny, ornately beset with dark brown granules, the periphery smooth 

 or pulverulent, changing from white or tawny to black; gills 7 mm. long, 

 1.2 mm. deep, narrowly adnate, without cystidia; spores 10 by 7 n, 

 black; stipe straight, 2.5 cm. or less high, 1 mm. thick, equal or slightly

Gimogon River, Negros, on wood of various kinds, and ground in chip- 

 yard, mostly solitary. Related to C. ^taudtii Hennings. 



C. Bryant! Copeland. Pileus passing from white through brown to 

 black, smooth, campanulate, G to 8 mm. high, 5 mm. wide, thin, odorless,

 brown, obtuse; stipe straight, white, solid, 2.5 to .3 cm. high, 1.5 mm.

 surrounded by white hairs 1.5 mm. long; veil obsolete; spores smooth, 

 brown, 8 by 4.5 /x, with hyaline, truncate apex. 



Gimogon River, Negros, on a rotten Ficus trunk; a smaller form collected 

 on rotten wood by the Baroring River, Mindanao. This is a real Coprinus, 

 in spite of the spore color of Bolbitius. It bears the name of H. C. Hryant, 

 of the Forestry Bureau, my host when it was collected. 



C. concolor Copeland. Odor none, taste mild; pileus conical, with 

 spreading margin, about 2.5 cm. high and wide, subfleshy, brown, very
