42. Poria Cokeri sp. no v. 



Appearing first in circular patches a few millimeters across, 

 then increasing to a centimeter, and finally becoming confluent in 

 areas 5 cm. or more long and 2 cm. wide, inseparable, rather thick, 

 especially at the center of the patches; margin coarsely radiate- 

 fibrous to membranous, conspicuous, 2-3 mm. broad when fairly 

 young, milk-white even when dry ; context white, membranous ; 

 hymenium somewhat uneven, white to slightly dirty-white, pale- 

 ferruginous where bruised; tubes quite rigid, irregular in shape 

 and size, 2-3 mm. long, concolorous within, mouths irregularly 

 rounded or slightly angular, usually 3, but sometimes only 1, to a 

 mm., edges entire to toothed ; spores rounded-ovoid, smooth, 

 hyaline, with a very distinct nucleus, 4x3^. 



Type collected on dead stems of a hedge of Ligustrum vulgar e 

 at Chapel Hill, North Carolina, December 9, 1914, W . C. Coker 

 1506. What appears to be the same species was collected on rot- 

 ting hardwood logs at Star City, West Virginia, May 3, 1907, 

 Carl P. Hartley 5/. 



43. Poria distorta sp. nov. 



Widely effused, following the irregularities of the substratum, 

 more or less continuous, separable, of medium thickness, drying 

 in concave, distorted masses; margin broad when young, white 

 to slightly discolored, cottony to membranous ; context white, con- 

 spicuous, tough, membranous, persistent ; hymenium very uneven, 

 often nodulose, white to cremeous or somewhat discolored ; tubes 

 often oblique, fairly regular in shape and size when fully mature, 

 1-2 mm. long, concolorous within, thin-walled, angular, 4-5 to a 

 mm., edges rather firm, entire to slightly toothed ; spores ellip- 

 soid, smooth, hyaline, 3.5x2.5^.

44. Poria submollusca sp. nov. 



Effused for several centimeters, continuous, inseparable, thin; 

 margin cottony, delicate, conspicuous, milk-white even in dried 

 specimens ; context white, membranous ; hymenium rather even, 

 white, slightly cremeous in dried specimens ; tubes mostly oblique, 

 showing a tendency to collapse at times, becoming irregular in
