Murrill: Light-colored Resupinate Polypores 85 



P. carneopallens was described from Spruce's collections in 

 Brazil, P. Fendleri from Fendler's collections in Venezuela, and 

 P. epilinteus from Ceylon. According to Cooke, one of the orig- 

 inal type specimens of the last species has orange mycelium while 

 the two others are without it. Poria cassicola Bres., recently de- 

 scribed from Brazil, is nearly related. Poria lilacina Speg., col- 

 lected by Balansa in Paraguay, is apparently not distinct. 



This species is rosy-isabelline when fresh, like P. eupora, with 

 which it is easily confused. It occurs throughout tropical regions 

 on dead wood of orange, acacia, etc., as indicated in the follow- 

 ing collections :

50. Poria albirosea sp. nov. 



Effused for several centimeters, continuous, inseparable; mar- 

 gin appressed, membranous, white to rosy-isabelline, becoming 

 inconspicuous with age ; context pallid, a mere membrane ; hy- 

 menium slightly uneven, not glistening, pallid to rosy-isabelline, 

 becoming pale-chestnut-colored in spots when bruised or handled ; 

 tubes rigid, rather regular, angular, 3-4 to a mm., reaching 2 mm. 

 in length, edges rather thin, entire ; spores ovoid, smooth, hyaline. 



Type collected on well-rotted deciduous wood at Fern Hollow, 

 Pennsylvania, July 13, 1906, David R. Sumstine 70. Also col- 

 lected at three different times on dead wood in Canada by Maconn 

 (probably near Ottawa), and at Wilmington, Delaware, Com- 

 mons 2672. Langlois' No. 2543, from St. Martinsville, Louis- 

 iana, may belong here, but the tubes seem rather small.
