Grows in dense fascicles about new stumps, and the base of 

 living trees ; also solitary and scattered among grass, but then 

 the mycelium is traceable to underlying tree-roots. Decidedly 

 parasitic and destructive. Extremely variable in appearance, so 

 much so that it is difficult to find two tufts alike. A form was 

 collected at Masham in 1891, with a blackish, shining stem. 

 Edible, but tough. 



Var laricina. 



S.W.— Halifax, 1788 (Bolton's Hist. Fung., Tab. 19). Liver- 

 sedge ('Nat.', 189T, p. 279).
