MURRILL : POLYPORACEAE OF NORTH AMERICA 597 



3. Inonotus dryophilus (Berk.) 

 Polyporus dryophilus Berk. Lond. Jour. Bot. 6: 321. 1847. 



The types of this species were sent from Ohio by Lea, who 

 collected them on living trunks of red oak. The fruit-body is 

 large and rigid, anoderm, ferruginous throughout, whitened ex- 

 ternally by a fine canescence, with thin, angular, brown pores. 

 The species resembles Polyporus dryadeus, but is smaller and more 

 rigid and has larger and differently colored pores. In some re- 

 spects it is allied to Hapalopilus gilvus, but the spores are deep 

 ferruginous instead of hyaline and the pileus is much thicker, with 

 a more obtuse margin. Excellent specimens are to be seen in 

 the Ellis collection, which were found by Morgan in Ohio in 1885. 

 He reports this species as occurring at the base of living oak trees 

 and on oak logs. 



4. Inonotus texanus sp. nov. 



Pileus ungulate, attached by the vertex, 3x5x4 cm.; surface 

 fulvous to fuliginous, concentrically and radially rimose, especially 

 in age, the separated areas imbricated ; margin very obtuse, concol- 

 orous : context corky, concentrically banded, fulvous to umbrinous, 

 very thin, only one-tenth the length of the tubes in thickness ; 

 tubes 3 cm. long, 2-3 to a mm., tawny chestnut, polygonal, edges 

 thin, entire ; spores ovoid, smooth, very dark brown, 1-2-guttulate, 

 8 x 10/i. 



The above description is based upon a single rather old sporo- 

 phore collected by Underwood on a mesquite (?) tree near Austin, 

 Texas, November 24, 1891. Although young stages are not rep- 

 resented, still the characters as shown are very distinct. 



5. Inonotus jamaicensis sp. nov. 



Pileus dimidiate to triquetrous, convex, sessile, attached by a 

 broad base, simple or imbricate, 2 X3 x 1-1.5 cm.; surface en- 

 crusted, minutely rugose, cinereous behind, marked toward the 

 margin with dark-brown or black zones ; margin regular, often 

 obtuse : context fibrous, fulvous, only a few millimeters thick ; tubes 

 1 cm. long, 4 to a mm., larger by confluence, fulvous, polygonal 

 to irregular, edges thin, entire ; spores ovoid, smooth, deep ferru- 

 ginous, i-2-guttulate, very copious, 5 x 7 ().. 



The type plants of this species were collected by Underwood 

 on the Mabess river, Jamaica, at an altitude of 3,000 ft., April 23, 

 1903. None of the young stages was found. Judging from the
