BURT — THE NORTH AMERICAN SPECIES OF CLAVARIA 47 



Polytrichum moss on a dry knoll at Middlebury, Vt. ; these clubs 

 were avellaneous when fresh. C. pallescens is closely related to 

 C. jumosa but its clubs are as closely crowded together at the 

 base as are those of C. jusijomm and do not become gray in color. 

 The illustration by Krombholz of C. jumosa shows the clubs 

 merely near together at the base but not actually touching one 

 another there, whereas Cotton and Wakefield state that the 

 species has the dense tufted habit of C. vermicular is. 



71. C. nebulosa Peck, Torr. Bot. Club Bui. 25: 326. 1898; 

 Sacc. Syll. Fung. 16: 207. 1902. Plate 8, fig. 72. 



Type: in N. Y. State Mus. Herb.; specimen from type collec- 

 tion, Waghorne, 227, is in Mo. Bot. Gard. Herb, and has been 

 compared with type. 



"Clubs simple, closely gregarious, 2.5-12 cm. high, fragile, 

 hollow, narrowed toward each end, isabelline or clay color, some- 

 times clouded with darker hues, apt to become blackish in dry- 

 ing; spores oblong or narrowly elliptical, 6-7.5 m long, 3.5-4 m 



broad. 



"Sandy soil, Sandy Point, Newfoundland. September. Wag- 

 horne." 



Has the aspect of a diminutive C. jistulosa but with the clubs 



densely tufted; spores hyaline, even, 6-7x3-3i/> p. Should be 

 compared with C. jumosa. 



72. C. lavendula Peck, N. Y. State Mus. Bui. 139: 47. 1910; 

 Sacc. Syll. Fung. 21: 431. 1912. Plate 9, fig. 73. 



Type: in N. Y. State Mus. Herb. 



"Tufts 2.5-4 cm. high, densely and subdichotomously branched, 

 the branches compressed, thin, lilac pink when moist, pruinose 

 when dry, the ultimate ones often bidentate, axils rounded; 

 spores minute, 6-8x3-4 |j. 



"Chestnut grove. Stow, Mass. July. S. Davis. 



"This species is related to Clavaria amethystina Bull., but it 

 differs in its flattened branches and smaller spores." 



The color of the type has faded to between pinkish buff and 



light buff; spores hyaline, even, 6X3 n- 



A fine collection of this species from the type locality, com- 

 municated by Miss Ann Hibbard and accompanied by water 

 color drawing, notes, and spore collection, shows the spores 

 white in the mass; the clubs are densely tufted, attenuated
