This species is not distinct from Thelephora pallescens 

 Schw., whose relationship to Hypochnus thelepJioroides (Ell. 

 & Ev.) Burt was pointed out in my comment on the latter in 

 Ann. Mo. Bot. Gard. 3 : 236. 1916. I have recently prepared 

 a new set of sections from the authentic specimen of Theleph- 

 ora pallescens Schw. in Curtis Herb. This specimen is in 

 fine condition and shows the spores fully as rough-walled or 

 aculeate in aqueous mounts as those of Hypochnus thelepho- 

 roides, which, therefore, becomes a synonym of T. pallescens 

 and should be displaced in my account of our species of 

 Hypochnus by the name Hypochnus pallescens (Schw.) Burt, 

 with synonymy and distribution as follows:
