Clavarias of the United States and Canada 145 



except the base, which is at first nearly white, but is easily stained 

 with vinaceous brown when handled. Flesh delicate, not so firm 

 as C. botrytis or C. flava and not snapping at a slight bend, but 

 more easily breaking than in most species, white, mildly bitter, 

 odor musty, faintly medicinal. 



Spores (of No. 2912) bufTy ochraceous, minutely rough, 

 3.9-4.4 x ll-13[x. Basidia 7.4-9.3[i. thick, 4-spored; hymenium 

 75-1 10(/. thick; hyphae 3-9[x, set with small crystals, often swollen 

 at septa but without clamp connections. 



This all-orange plant varies into other color forms: one, 

 represented by No. 2882a, in which only the tips are orange, the 

 remainder when young, creamy flesh, then creamy tan; another 

 (No. 2597) in which the plant is brownish tan with a dull pink 

 tint, the base stained with deeper brown when rubbed. 



Distinguished by the quick branching from a short, pointed, 

 slightly rooting base, by the stains on basal region, by the fine 

 rich color, by great delicacy, by absence of krauty odor or taste, 

 and by the long, narrow spores. It is evidently a close relative 

 of C. rufescens. It may be this species that is interpreted as C. 

 flava by Bresadola, one of the foremost living mycologists. In 

 his Fung. Mang., p. 108, he describes the species in a way that 

 seems to exclude all others. He mentions the uniform yellow 

 ("sulfur yellow") color, the wine-red stains on the stem and the 

 elongated cylindrical spores, 4-5 x 10-14[/. long. At the New York 

 Botanical Garden is a plant from him labelled C. flava which 

 looks like our C. aurea var. australis and with spores faintly rough, 

 4-4.5 x 9- 10.5 [x. That this is really the C. flava of Schaeffer 

 seems highly improbable as such an interpretation is at variance 

 with the opinion of most European and American students of the 

 group. See under C. flava for further discussion.

 upland woods, July 5, 1917. Spores ochraceous, elliptic with a large
