The types of most of these names have been seen. Berkeley’s 
as is with his own specimens at Kew. Specimens illustrative - 
Desmaziére's, Westendorp's, Fischer de Waldheim's, Fuckel's, 
Ule's and Karsten's names authenticated by these writers have 
been seen. Sydow’s Myc. March., 2120, if correctly named, 
determines T. mb a to be a form of T. de Bar aryana, 
Lastly, Ule's very unsatisfactory account of T, Brizæ makes this 
appear another form of the same species.
