Clavarias of the United States and Canada 157 



when dried, and by the different spores. From the latter it may 

 also be separated by the white tips and mild taste. The color 

 when dried is somewhat like that of C. gracilis at times, but that 

 has more open and divaricated branching - and very different 

 spores. That our plant is C. Patouillardii is shown by comparison 

 with that species in the Bresadola Herbarium (Stockholm), which 

 is alike in all details, with the same peculiar farinose-nocculent 

 mycelium. The spores are narrow, pointed-elliptic, smooth, 

 2.5 x 6.3-8[k. This was growing on f rondose trash, but a collec- 

 tion by Patouillard in the herbarium of the University of Paris 

 was taken from coniferous leaves and twigs. The description and 

 figures agree in every detail. A plant from Bresadola at the New 

 York Botanical Garden labelled C. Patouillardii var. minor has 

 exactly the same spores (hyaline, smooth, 2.3x7[a) and the same 

 mycelium. Clavaria decurrens var. australis is most like the pres- 

 ent species in appearance when dry. 



Pennsylvania: Bethlehem. Schweinitz. (Schweinitz Herb., as C. byssi- 

 seda). The plants seem like this species in the dry state and the peculiar 

 spores are identical, hyaline, smooth, 2.3 x 7.7/j. 



New York : Vaughns. Burnham. Several collections in rotting leaves or 

 in humus near decaying deciduous wood, July, 1916, and July, 1917. 

 Spores alike in all. Also C. & B. No. 101a. In Burnham's hemlocks 

 growing near C. flaccida and C. sabdecurrens, Sept. 2, 1917. Spores as 

 above, 2.3 x 7-7.7/1. (U. N. C. Herb.).

Plants of small or medium size, up to about 7 cm. high, 

 crowded or single, branched from or near the base, the slender 

 stems springing from abundant fibrillose mycelium or when on 

 bark often fusing into an amorphous, white, flattened, tomentose 

 tissue which extends between the layers. Main stems about 3-4 

 mm. thick, branching quickly into curving, somewhat flattened, 

 elongated branches, the angles rounded, the ultimate branches 

 ending in two or three long, sharp tips, which are straight or 

 divaricating and whitish in youth; surface white-tomentose at 

 the protected base, smooth elsewhere except scurfy tomentose
