Mycologia 



amorphus. Tyromyces amorphus (Fries) Murrill, Mycologia 

 10 : 109. pi. 6, f. 5. 1918. Rare on conifers in northern 

 regions. 



amygdalinus. Polyporus amygdalitius Berk. & Rav. ; Berk. Gre- 

 villea 1 : 49. 1872. Described from South Carolina, on oak, 

 and poorly represented until Dr. R. P. Burke recently sent me 

 splendid specimens from Alabama. They suggest Laetiporus 

 sulphureus, but are not brilliantly colored and the context is 

 very soft corky instead of rigid when dry. 



Arctostaphyli. Fomes ArctostaphyWLong. Compare depauper- 

 ate forms of Pyropolyporus igniarius. 



auriculatus. Pseudofavolus auriculcttus Pat. Bull. Soc. Myc. 

 Fr. 24: 4. 1908. Described from Louisiana and said to re- 

 semble Hexagona cucullata (Mont.) Murrill. 



borealis. Fomes borealis C. G. Floyd, Syn. Fomes 247. 191 5. 

 Type not seen. Apparently a species of Pyropolyporus. 



" Pileus ungulate, with a thin, pale, smooth, hard crust, variegated with 

 darker spots. Context hard, dark brown (amber brown). Setae slender, 

 numerous, dense. Spores hyaline, globose, 6 fx. 



" I found this on the birch at Temagami, Ontario. It is closely related to 

 igniarius and nigricans. The marked feature is the dense setae on the 

 hymenium." 



Brownii. Elfvingia Brownii Murrill, Western Polypores 29. 



191 5. Found in California. 

 caesiosimulans. Tyromyces caesiosimulans Atk. Ann. Myc. 6 : 



61. 1908. k Said to be near T. caesius, but to have globose. 



pedicellate spores. 

 calvescens. Polyporus calvescens Berk. Ann. Nat. Hist. 3 : 390. 



1839. Described from New Orleans, Louisiana, and not since 



collected. 



carbon arius. See Tyromyces carbonarius Murrill in Western 

 Polypores, p. 8. 



confluens. Polyporus confluens (Alb. & Schw.) Fries. I have 

 examined many specimens in herbaria and have studied fresh 

 plants with Bresadola at Mendel Pass, but nothing I have seen 

 from America seems to match it. It is pale-red at first, be- 

 coming almost as brilliantly colored as Hypomyces lactifluorum. 

 Mr. Lloyd reports having seen a specimen from Massachusetts 

 collected by Mrs. Blackford.
