sterile. Peck announced (Bull. Torr. Club, 188^, p. i) that the spoies are borne 

 on basidia (not in asci as previously supposed) and he established for it a new 

 genus Physalacria, now generally classed with the Clavariaceae. There has been 

 but this one species found in northern United States and it is rare. Ellis 

 claimed to have found a new species from Louisiana, which is unknown to me.

THE GENUS FISTUUNA. The genus Fistulina is based on 

 the character of separate tubes. In general appearance the tubes re- 

 semble the pores of a Polyporus, but in the latter the walls of the 

 pores are not separated from each other, and in Fistulina each tube 

 is separate and distinct. Our enlarged photograph (Fig. 220) will 

 show this tube structure as we think never before illustrated. 6 We 

 have two species of Fistulina in the United States, both of them 

 rather rare. 



6 Excepting by De Seynes. The best work ever done with this genus was by De Seynes, 

 and of the many illustrations published in Europe I think his truest to nature.
