This is Intermediate in size between T. personatum and T. ionidi 

 and all ihree have similar colors. T. ionides, which has been re- 

 ported from the state by Longyear, is known by its conic-campan- 

 ulate pileus, which is at ti rst flocculose on tin- margin, its stuffed 

 tn hollow stem, and whitish gills and spores; its cap is 2-5 cm. 

 broad. Buyol (Soc. .Myc. de France, Vol. L6, p. 95 i states thai 

 it can always be distinguished, since the flesh of the stem is uni- 

 formrj blue, while that of T. personatum is pallid or grayish. Peck 

 Bays the stem of his plants was stuffed or hollow, while European 

 authors describe it us solid. The spores, as in '/'. personatum, are 

 pale flesh color, and show the relation of these plants t<> the rosy- 

 spored group; bu! as it is now pretty well admitted thai the sum of 

 the other characters of a planl are of mine generic importance than 

 the spore-color, especially where 11 is no1 very marked, i1 would 



seem hest to keep them ill this genUS.
