116 MURRILL : POLYPORACEAE OF NORTH AMERICA 



8. Pyropolyporus Underwoodii sp. nov. 



A blackish ungulate plant of large size with furrowed rimose 

 surface and long brown tubes. Pileus woody, broadly ungulate, 

 attached by a narrow base, concave below, 7 X 14 X 1 1 cm.; sur- 

 face many times concentrically furrowed, rimose, uniformly dark- 

 brown to black ; margin fulvous, acute or somewhat obtuse, vel- 

 vety, undulate, marked with narrow zones : context hard, fulvous 

 to dark brown, very thin, less than 0.5 cm.; tubes distinctly strati- 

 fied, 0.5-1.5 cm. long each season, 3 to a mm., brown within, 

 mouths darker, circular or polygonal, edges acute, entire : spores 

 ellipsoidal, smooth, thin-walled, Hght yellowish-brown, 7X9-". 

 cystidia none. 



Collected by Underwood and Griggs during the summer of 

 1 90 1 near Coamo Springs, Porto Rico. The plant reminds one 

 of P. Rohmiae, but differs very widely in tube-structure, as well as 

 in color, density and spore characters. 



9. Pyropolyporus juniperinus (Schrenk) 

 Polyporiis juniperimis Schrenk, U. S. Dept. Agr. Veg. Physiol. 



Bull. 21: 9-16./'/. 1-4.. 1900. 



So far as I know, there are only two specimens of the fruiting 

 stage of this plant in existence, one collected by Schrenk in Ten- 

 nessee and the other by Miss Sadie F. Price in Kentucky. The 

 latter specimen, the better developed of the two, was sent to the 

 Underwood herbarium in 1895. 



Both specimens were found upon Jiuiipenis Virginiana, the 

 wood of which is badly affected by its mycelium. The statement 

 made by the author that the discovery of other specimens might 

 prove this species to be only a form of P. fomcntarms is entirely 

 unnecessary, since such connection between two plants so distinct 

 is beyond the range of possibility. 



10. Pyropolyporus Earlei sp. nov. 



A broadly ungulate plant with yellow pores, red context and 

 a dark very rimose surface. Pileus woody, attached by a broad 

 base, plane below, 6 X 13 X 17 cm.; surface concentrically 

 sulcate, very rimose in older parts, fulvous to brownish-black, 

 at length grayish-black from weathering ; margin broad, obtuse, 

 dark yellowish-orange, clothed with short dense tomentum of the 

 same color : context woody, dark reddish-orange, concentrically 

 banded with darker lines, very thin, 0.5 cm., rimose down to the
