In oak woods, rare. Pileus 1-2 inches broad, the stipe less 

 tlian an inch in length. 



II. Pleuropus. Pileus more or less dimidiate, the stipe lat- 

 eral. 



5. H. ADUSTUM, Schw. Pileus variable in shape from orbic- 

 ular and entire to dimidiate and reniform, coriaceous-tough, 

 whitish or pale yellowish. Stipe ascending, unequal, subcentral 

 or lateral. Aculei at first pallid or yellowish, then changing to 

 brown or blackish. 



In woods on fallen sticks and branches, not rare. Pileus 2-3 

 inches broad, the stipe an inch or less in length. The pileus in 

 very thin, velvety or nearly smooth, more or less zonate, sometimes 

 brownzonate. The stipes are sometimes concresent, with separate 

 or more or less united lobed and overlapping pilei. 



III. Merisma. Very much branched or tuberculiform and 

 immarginate. 



6. H. CORALLOIDES, Scop. Very much branched, pure white; 

 finally changing to yellowish and the whole plant expanding into 

 attenuate intricate branches. Aculei unilateral, subulate, entire. 



In woods on old trunks, common. A very showy plant> 

 sometimes a foot or more in extent, when fully developed consist- 

 ing ot numerous intricate branches with the spines pendent from 

 the lower sides. It is said to be edible. 



7. H. ERiNACEUS, Bull. Fleshy, elastic-tough, pendulous, 

 tuberculose, immarginate, white, changing to yellowish, fibrillose, 

 lacerate above. Aculei very long, straight, equal, pendulous. 



In woods on old trunks, not rare. Of a rounded form 4-8 

 inches in diameter, sometimes with the rudiment of a lateral stipe ; 

 appearing solid but when broken open it is found to be a mass of 

 interlacing branches. The spines are remarkably long, from 1-2 

 inches or more. 



8. H. STRATOSUM, Berk. Pilei resupinate, with a narrow 

 lobed border, consisting of repeatedly branched rigid brown pro- 

 cesses, which are clothed above with gray or ferruginous tow-like 

 fibers. Aculei rather long, rigid, sharply acuminate, brown vary- 

 ing to cinereous, at length stratose. 



On a dead trunk (^Lea). Pilei sjireading for 3 or 4 inches over 

 the matrix. "This is one of the most remarkable species with which 

 I am acquainted." "I do not know any other species with which 

 it can be compared." {Berkeley va. Lea's Catalogue.) This appear
