Plants of moderate to good size, up to 11 cm. high and same 

 breadth, base as in C. botrytis, tapering, somewhat rooting; 

 branching at the ground into several rather slender, at times 

 broadly spreading, main branches, and in nearly all cases with 

 several or numerous small undeveloped peripheral ones at the base ; 

 main branches soon rebranching several times in an irregular 

 manner to form a rather open mass, the ultimate tips usually deli- 

 cate, but at times much thickened and blunt (as in No. 560), 

 more or less cusped; surface more or less rugose upwards; color 

 clear, not at all tan or ochraceous, varying from a clear pale cream 

 (in Nos. 1850 and 1855) to a light creamy yellow (maize-yellow 

 of Ridgway), or in the northern form to a deep, rich, clear prim- 

 uline or chrome yellow (Ridgw.) in youth, but becoming much 

 paler at and after maturity. The color is about the same through- 

 out in the pale form or paler downwards in the richer colored 

 forms, only the very base whitish at the ground and not turning 

 rose-wine when bruised, as in C. aurca var. australis and C. rufcs- 

 cens ; tips concolorous when fresh, but usually turning a pale, clear, 

 soaked brown and then a darker brown when fading; if dried 

 quickly this change in color of the tips does not appear. Flesh 

 very brittle, not white, but when quite fresh colored like the sur- 

 face, or at least with a tint of cream (rarely almost colorless) ; 

 taste and odor very pleasant, distinctly krauty (faintly like green 

 peanuts). W(hen very young the entire plant is nearly white, the 

 tips pure white and without a trace of pink. 



Spores (of No. 2855) about maize-yellow (Ridgw.), minutely 

 rough, elliptic, 3-4 x 7.4-10[x.
