This beautiful species which is usually pure white is known in 

 North America only from North Carolina and was described by 

 Professor Atkinson as a new species from plants collected by us. 

 It seems almost certain, however, that it had been published twice 

 before from South America. Atkinson's description is as follows : 



"Plants stalked, very much branched, 3-4 cm. high, branching, 

 2-3 cm. broad. Stems slender, about 3 mm. in diameter. Pri- 

 mary branching dichotomous or subpalmate. The branches 

 branching in a similar way, more or less flexuous and often 

 slightly flattened. Axils acute or rounded. Plants entirely 

 white, flour-white, soft, flexible, not brittle. Spores white, angu- 

 lar to tuberculate like the spores of some species of Inocybe, 

 3-3.5 x 5-7[i.. C. U. Herb., No. 22641, on ground, mixed woods by 

 Fern Walk near Sparrow's Pond, Chapel Hill, N. C, W. C. 

 Coker, October 2, 1908." 



The plant is abundant in humus or rotting wood in deciduous 

 woods near branches in Chapel Hill during summer and fall and 

 since the above description was written we have made numerous 

 other collections, some of which were much larger plants than the 

 first. Our description follows : 



Plants 3-11 cm. high, and 2-8 cm. broad. Stalks long and 

 slender and extended below into an obvious, thready, white my- 

 celium ; main branches often much flattened upward in an antler- 

 like fashion, terminating in numerous, short, flattened, pointed 

 branchlets ; entire plant pure chalky white as a rule, but occasion- 

 ally varying to pale pink especially upward, tough and quite pliable 

 to rather rigid and moderately brittle; taste pleasant and mild; 

 odor distinctly of old ham.
