MURRILL : POLYPORES OF TEMPERATE NORTH AMERICA 23 



smaragdinus. Polyporus smaragdinus C. G. Lloyd, Myc. Notes 

 58:818. /. 1365. 1919. Collected by Dr. J. F. Brenckle on a 

 sycamore log in Arkansas. Type not seen. 



" Tileus dimidiate, 1-2 inches thick. Surface dull, uneven, with thin, 

 buff cuticle. Context white, hard when dry. Pores minute, 4-6 mm. deep, 

 with pale greenish tissue and brown mouths. Cystidia none. Spores globose, 

 hyaline, 6 /n. Conidial spores abundant, small, subglobose, 2-3 hyaline. 



" The colors are those of the dried specimen. I judge that of the pore 

 mouths has changed in drying. The pale green pore tissue is an unusual 

 feature. I do not recall it in any other species." 



spumeus. This species has several times been reported, but I 



have seen no American specimens that correspond with those 



I have from Europe. 

 subpendulus. Tyromyces subpendulus Atk. Ann. Myc. 6: 61. 



1908. On hemlock ; resembling Porodisculus pendulus in 



shape. Type not seen. 

 substipitatus. See Tyromyces substipitatus Murrill in Western 



Polypores, p. 9. 



tephroleucus. Reported from America, but I have seen no 

 American specimens that correspond with European material. 



torulosus. Fomes torulosus Pers. Reported by Lloyd from 

 Louisiana, growing on live oak. He says that Fomes fuscopur- 

 pureus Boudier, pp. 152, is the same thing and that the spores 

 are hyaline. I have not seen the Louisiana specimens, unless 

 they were some I determined for Edgerton as Hapalopilus 

 licnoides. This species gets quite thick at times and appears 

 to be perennial. 



ursinus. Polyporus ur sinus C. G. Lloyd, Syn. Apus Pol. 319. 

 f. 659, 660. 191 5. Type not seen. Compare the description 

 carefully with Spongipellis fragilis (Fries) Murrill. 



" Pileus dimidiate (i X SX 7 cm.), white, but turning reddish when 

 bruised and on drying. Surface strongly scrupose, tomentose, with rigid, 

 tufted hairs, which have the same color change as the flesh. Flesh white, 

 soft when fresh, but drying firm and hard. Pores medium large, sinuate, 

 white, discolored in drying. Spores narrow-piriform, tapering to the base, 

 2 y 2 X 8-10. 



"This we collected growing on pine at Temagami, Ontario, August, 1907. 

 We referred it, from the description, with which it agrees exactly, to Poly- 

 porus Weinmanni of Europe, but we find the type of the latter plant at Kew is 

 quite different, being Polyporus mollis. We think Professor Peck has col-
