 15. Balmoral, April 16, 1884, /. Micliie ; on dead trunk oi Pinus 

 sylvestris, Braemar, July, 1884, G. Stabler. 



Found on the Continent and in North America. 



Obs. — This very rare and small species is not likely to be 

 confounded with any other; it grows on rotting wood, which is 

 its only habitat. 



Lindberg reduced it to a variety of hhJiuu/. verrucnlosa(l874:), 

 but as it is a very distinct and full}^ developed species, I do not 

 see any reason why Nees's name Ji/n//. Helleriana (1829) should 

 have been superseded. Later (Medd. Soc. F. Fenn. 14, p. 65 

 (1887), be removed it to CephaJozia, in which he has been 

 followed b}^ Dr. Kaalaas.
