COPRINUS EBULBOSUS. 
__ Pileus thin, campanulate, variegated by the cuticle breaking 
into broad superficial persistent whitish scales, the surface beneath 
the cuticle somewhat striate, grayish-brown, the margin at length 
revolute, lacerated; lamellae narrow, thin, crowded, free, slate 
color becoming black; stem equal, hollow, white; spores ellipti- 
cal, .0003 to .0004 in. long, .0002 broad. 
Pileus 2 to 3 in. broad; stem 3 to 6 in. long, 2 to 3 lines 
thick. |

This plant resembles C. picaceous very closely. New York 
specimens were formerly referred to it as variety edalbosus, but 
having now received it from various widely separated localities 
and finding that it maintains its distinctive characters with con- 
__ Stancy, it seems best to consider it a good species. Its peculiar 
characters are the absence of a bulbous base to the stem and its 
smaller spores. It also sometimes grows in large tufts. “ About 
fifty grew in a solid clump, all united at the base.” 
COPRINUS LANIGER. 
Pileus thin, conical or campanulate, covered when young with 
numerous tawny tomentose or floccose scales which partly or 
wholly disappear with age, sulcate-striate nearly to the apex, 
Pallid, tawny or grayish-ochraceous; lamellae crowded, at first 
whitish, then brownish-black; stem slightly thickened at the 
base, minutely downy or pruinose, hollow, white; spores oblong- 
elliptical, commonly uninucleate, .0003 to .0004 in. long, .00016 
broad. 
Pileus 6 to 12 lines broad; stem about 1 in. long, 1 to 2 lines 
thick.

The species resembles C. micaceus, from which it is distin- 
: guishable by the floccose-squamose coating of the young pileus 
and by its more narrow spores. Mr. Bartholomew remarks that 
“it is of slow growth, taking three or four days for development.”
