namon colored spines. The pileus of specimens received is dark col- 

 ored, but appears to me as though weathered, and I presume the 

 natural color is cinnamon. The plant came from the province of lyo 

 and I suppose the name is lyo latinized. In this connection, it is 

 strange that our most abundant Irpex cinnamomeus has not been 

 found in Europe or Japan. 



THELEPHORA FLABELLARIS, FROM DR. M. S. WHET- 

 STONE, MINNESOTA (Fig. 904). This is a rare form. With 

 same texture and surface as Thelephora caryophyllea, it is cut into 



Fig. 904.

narrow segments. Berkeley who collected it in England, followed 

 Fries in holding it as an "irregular branched frond" of Thelephora 

 caryophyllea. I doubt it although it is so rare, it is hard to say. I 

 never saw but three specimens, the English plant at Kew, a collection 

 from O. M. Oleson, California, and this one from Mrs. Whetstone. 



THE TROPICAL XYLAR1AS. 



The principal published work on the foreign Xylarias has been 

 done by Cooke, who arranged and illustrated a series of figures. It 

 is needless to say to those who have checked up after Cooke's work 

 that it was very inaccurately done, and that many of his figures 

 were simply reconstructed. The more recent workers, Rehm and 

 Theissen, who have not studied the authentic types, have evidently- 

 reached many of these conclusions, mainly from Cooke's work, with 

 the natural result that they have still further added to the con- 

 fusion. I have never given the subject the detailed study in the 

 museums that I would have wished, but I have photographed all the 

 type specimens I found, and with these photographs and with the 

 published accounts I think I can reach much more correct con- 

 clusions than have been previously recorded. 



I shall be very glad if my correspondents will collect and send 

 me the Xylarias that they note. These plants have a young, conidial
