lobose. 5-7 u in diameter 



Among grass in woods and pastures. 



Cotton and Wakefield add further: "C. amethystina has some- 

 what the habit of a short thick form of C. cinerea, with the deep 

 colored forms of which it has by some authors been confused. 

 When once the true plant has been seen, however, there is no 

 difficulty in distinguishing it by its beautiful violet color (almost 

 as deep as that of Laccaria laccata var. amethystina), and by its 

 smaller spores." 



Peck has collected this species in New York; I have referred 

 a Vermont Catherine here.

"Clubs 2-4 cm. tall, with few rather short suberect branches, 

 very pale-lilac, becoming drab-gray in drying, the branches often 

 compressed and rugose, more or less pruinose when dry, the tips 

 commonly acute; spores globose, 8 \i in diameter.

"This species is evidently related to C. amethystina Bull, and 

 C. Schafferi Sacc. From the former it is separated by its differ- 

 ent mode of branching and its globose spores; from the latter, to 

 which it seems more 4 closely allied, by its simple, not cespitose 

 mode of growth, by the acute or mucronate tips of the branches, 

 and by the pruinose character of the branches, which also are 

 often rugose and irregular." 



Fructifications now with trunk and main branches tawny olive 

 and the terminal blanches discolored somewhat olive-brown and 

 pruinose; main stem somewhat compressed and twisted in drying, 

 the terminal branches more cylindric, rather stout, irregular, 

 usually obtuse; spores hyaline, even, subglobose, 6-7x5-6 n, 

 copious.

"Very small; stem slender, dichotomously or somewhat irreg- 

 ularly branching, white, branches delicate lavender color or the 

 lower white toward the base, tips subacute, axils rounded; spores 

 minute, globose, .00008-0001 of an inch broad.
