BURT THE THELEPHORACEAE OF NORTH AMERICA. XIV 289 



spores hyaline, even, narrowly cylindric, slightly curved, about 



4H-7 x iy 2 n. 



Fructifications 3-10 cm. long, 1-3 cm. wide. 



On decaying pine wood. Europe, New Jersey to Louisiana, 

 and in Washington. July to March. Rare. 



The cystidia of P. subalutacea place it in the group with P. 

 glebulosa and P. crassa. It is thinner than either of these. It 

 may be distinguished from thin forms of the former by the thin- 

 walled cystidia which have a lumen of nearly uniform diameter 

 which is not abruptly and greatly enlarged near the apex of the 

 cystidium.
