202 Clavarias of the United States and Canada 



New Hampshire: Chocorua. Farlow. (U. N. C. Herb, from Farlow 



Herb.). 

 California: Pasadena. McClatchie. (N. Y. Bot. Gard. Herb.). 



Typhula phacorrhiza (Reich.) Fr. Obs. Myc. 2 : 298. 1818. 



In form and appearance in the dried state this is scarcely dis- 

 tinguishable from T. juncea except for the base, which springs 

 from a flattened disc-shaped, shining brown tuber or sclerotium, 

 the base of the stem just above the tuber being clothed with a 

 rather dense tuft of hair in specimens we have seen. 



The clubs are variously described as white or pallid or pale 

 fuscous. The microscopic structure except for the spores is al- 

 most identical with that of T. juncea, the flesh delicate and flexible 

 and composed of densely compacted, parallel cells, surrounding a 

 small, clean-cut hollow. 



Spores (in plants from Portville, N. Y.) elliptic, smooth, hya- 

 line, 4.4-5 x 9-14(1.; basidia 4-spored, about 55[x thick. A good 

 collection from Seattle, Wash., by Murrill has exactly the same 

 appearance and structure; spores 4-5.9 x 9.3-14.8(1.; basidia 4- 

 spored, 5.5(jl thick. Of this last Murrill has the following note 

 on the fresh condition: "On leaf mold, gregarious, abundant, 

 about 12 cm. high and 0.5 mm. thick, pale fulvous, shining [aris- 

 ing] from a flattened, double, seed-like sclerotium." This refer- 

 ence to a "double" sclerotium refers to the fact that some (or 

 most) of the plants arise from the margins of two sclerotia, one 

 on each side, and connect them, looking like a shoot between two 

 flat cotyledons. The plants from New York show only one sclero- 

 tium to a plant, but this is the only difference we can find except 

 that the Seattle plants are twice the height. We do not know if 

 T. incarnata Fr. is really different from the present species. De- 

 scriptions lack the detail necessary for a decision. Our plants 

 seem to be just like those shown by Greville in his plate 93 (as 

 Phacorrhiza filiformis). Sowerby's plate 233 (as Clavaria pha- 

 corrhiza) may or may not be the same. 



PTERULA 



Slender and filiform throughout, small, in our species much 

 branched from a distinct stalk; texture elastic, toughish, not
