WESTERN POLYPORES 21 



spores subglobose, smooth, 8-10 X 7-8 /z, the outer wall hyaline, 

 the inner membrane brown; cystidia 15-35 X 5-9 A*. 



Occasional in California as a root parasite of various species 

 of oak, the large hymenophores appearing near the base of the 

 trunk. Attention is called to recent studies of this species and 

 the next by W. H. Long. 



3. INONOTUS DRYOPHILUS (Berk.) Murrill 



Pileus thick, unequal, unguliform, subimbricate, rigid, 7-8 

 X 10-14 X 2-3 cm.; surface hoary-flavous to ferruginous- 

 fulvous, becoming scabrous and bay with age; margin thick, 

 usually obtuse, sterile, pallid, entire or undulate; context fer- 

 ruginous to fulvous, zonate, shining, 3-10 mm. thick; tubes 

 slender, concolorous with the context, about I cm. long, mouths 

 regular, angular, 2-3 to a mm., glistening, whitish-isabelline to 

 dark-fulvous, edges thin, entire to toothed; spores subglobose, 

 smooth, deep-ferruginous, 6-7 /JL; cystidia scanty and short. 



Frequent in California and Oregon on living or dead oak trunks, 

 causing serious decay. 



4. INONOTUS LEEI Murrill, sp. nov. 



Hymenophore resupinate, immarginate, rigid to fragile, effused, 

 15-40 cm. broad; context fulvous, inconspicuous; tubes 1-3.5 

 cm. long, slender, cylindric, fulvous, 3-4 to a mm. at the base, 

 larger at the mouths, rather thick-walled, not stratified; mouths 

 ungulate, irregular in size and shape, 1-4 to a mm., citrinous- 

 stuffed, edges thin, becoming slightly toothed and blackish with 

 age; spores subglobose to ellipsoid, smooth, melleous under a 

 microscope, uniguttulate, 6-7 X 5-6 n; hyphae fulvous, 3.5-4.5 [*', 

 cystidia fulvous, cuspidate, small and variable. 



Type collected 15 feet above the ground on a decayed trunk of 

 Quercus agrifolia on the University of California campus, Berke- 

 ley, California, April, 1914, H. A. Lee (herb. N. Y. Bot. Card.). 

 Also collected on the same host in the same locality by students 

 of the department of botany of the University of California; and 

 on a fallen log of Quercus agrifolia at Stanford University, Cali- 

 fornia, March 13, 1912, James McMurphy igi. This very in- 

 teresting anomalous species extends for several square feet over 

 the surface of decaying trunks of the common live oak, which it 

 undoubtedly injures very seriously. It is hoped that pileate 

 specimens will be found so that the description may be completed.
