116 Clavarias of the United States and Canada 



Clavaria subbotrytis n. sp. 



Plates 28, 33, and 85 



Plant 7.5-10 cm. high, 5.5-9 cm. broad, branches numerous, 

 upright, close; tips not terraced, short, bluntly rounded; color 

 coral pink all over when young, fading to creamy ochraceous ex- 

 cept in the upper part at full maturity (the stem base remaining 

 pinkish or white). Flesh concolorous and remaining pink longer 

 than the surface, tender but hardly so brittle as in C. botrytis; 

 odor and taste slightly krauty. Stem short but clean and smooth, 

 glabrous and without aborted twigs, tapering to a clean point be- 

 low. 



Spores (of No. 4679) nearly smooth, elliptic, cinnamon- 

 ochraceous, with a distinct tint of rose in the denser parts of a 

 print, 3-3.7 x 7.4-%. Basidia (of No. 3297) 6.5-9.5[x thick, 

 irregular, 4-spored; hymenium 55-65[x thick; threads of flesh 

 variable in diameter. No clamp connections seen. 



Distinguished from C. botrytis by the deeply colored spores, 

 the clean, smooth, sharply pointed stem, pink color all over until 

 near maturity (the upper part remaining pink until well after 

 maturity), absence of sharply contrasting red tips in youth, and 

 by the quite different appearance in the dry state. Distinguished 

 from C. conjunctipes var. odora by slight odor, narrower and 

 rougher spores, much more solid and brittle flesh, the threads of 

 which are narrower ; much deeper flesh color with tips soon con- 

 colorous ; base not so slender and plants not so compound towards 

 base. From C. formosa, which has yellow tips in youth, it differs 

 in greater brittleness, deeper pink color, narrower and smoother 

 spores of a more cinnamon color, and in the quite different tex- 

 ture when dry. The imbedded part of the stem base may be 

 either pink or white. In No. 4679 it remained pink after the 

 central region of the plant had turned ochraceous. Wounds and 

 bruises do not turn red or wine color. When quite young the 

 very tips were creamy in No. 2621, but soon lost this and became 

 concolorous. In No. 4679 this was not obvious as the plant was 

 nearly mature when collected. 



North Carolina: Chapel Hill. No. 2621. At base of a hickory tree, low 

 damp woods, near Woodland Theatre, July 9, 1917. Pink all over ex- 

 cept for the very tips which are creamy in youth. Spores very minutely
