51. Poria subundata sp. nov. 



Effused for several centimeters, becoming continuous, closely 

 appressed, inseparable, thin ; margin inconspicuous, thin, ap- 

 pressed, white, soon disappearing; context pallid, not apparent 

 in age; hymenium very oblique, beautifully undulated, not glis- 

 tening, cremeous to pale-rosy-isabelline ; tubes small, rigid, regu- 

 lar in size and shape, angular, 5 to a mm., 1 mm. or less long, 

 edges thin, entire ; spore characters not satisfactorily determined. 



Type collected on a decayed standing stub of a hardwood tree 

 in wet woods on Cooper's Ranch at the base of El Yunque Moun- 

 tain, Baracoa, Cuba, March, 1903, L. M. Underwood & F. S. 

 Earle 1168. Also collected on decayed hardwood in Troy and 

 Tyre, Jamaica, January, 1909, W. A. Murrill & W. Harris 1012. 



52. Poria subincarnata (Peck) sp. nov. 



Poria attenuata subincarnata Peck, Ann. Rep. N. Y. State Mus. 

 48: 118. 1897. 



Briefly described by Peck as follows, from specimens collected 

 on fallen branches of Tsuga canadensis at Alcove, New York, by 

 C. L. Shear in November, 1893 : 



" This differs from the typical form in the paler color of the 

 pores. It grows on hemlock bark and forms small patches rarely 

 more than 1 inch in diameter." 



Overholts has described it at length after studying type ma- 

 terial and specimens recently collected by himself in New Hamp- 

 shire. He finds the spores allantoid, hyaline, 4-5 xi/i;, cystidia 

 none. I have a number of collections — on fir, hemlock, Cnpres- 

 sus thyoides, alder, maple, etc. — all of which appear to be iden- 

 tical with the type at Albany. Various specimens collected by me 

 in Maine and New York appeared milk-white to buff with an in- 

 carnate tint when fresh and are now pale-rosy-isabelline in the 

 herbarium. Thin forms of Poria eupora from Karsten collected 

 on willow greatly resemble this species at first glance, but under 

 a hand lens they show darker and more rosy tints, while the 

 microscope reveals their strikingly different spore characters.
