i G52 MuRRiLL : Polyporaceae of North America 



Polystictits barbatuhis Fr. Nov. Symb. Zj, 185 1. 



Described by Klotzsch from North American specimens in the 

 Hooker herbarium. The type collection of Polystictus barbatuhis 

 was made by Curtis in South Carolina on dead trunks of red cedar. 

 Fries separated it from Hexagona scricea because of its large 

 pores, not knowing that this species shows wide variation in the 

 form and size of its tubes. The resupinate depauperate form' is 

 incorrectly called Poria snperjicialis of Schweinitz in the Fries 

 herbarium. 



This plant is distinct, easily recognized and confined to one 

 host, Jnniperns virginiana^ on the dead trunks and branches of 

 which it is quite common in the southern United States north to 

 Virginia and west to Missouri. I have collected it in quantity 

 near Elizabethtown, Tennessee. 



Specimens have been examined from South Carolina, Ravenel ; 

 Georgia, Ravenci ; Florida, Rati^ Calkins^ Lloyd ; Louisiana, Lang- 

 lots; Tennessee, Miirrill 456; Kentucky, Miss Price ; Missouri, 

 D erne trio. 



21. Coriolus arenicolor (B. & C.) 



Polyporus arenicolor B. & C. Jour. Linn. Soc. Bot, 10 : 3 1 5. 1 868. 

 Described as follows from Wright's collections in Cuba : 



' Pileo dimidiato postice decurrente papyraceo repetite zonato strigoso velutino, 

 pallido, inargine lobato ; poris parvis angulatis, dissepimentis tenuibus ; hymenio 

 ochraceo." 



'* On logs in woods. Pileus 3 inches wide, X% long. Pores j^^ inch across. 

 Allied to P. pinsitits rather than to P, /iirsntus,^^ 



This is a very abundant species throughout the West Indies, 

 on dead sticks and logs of various broad-leaved trees. It has 

 been confused with C, velutinns and with C. haedinnSy from both 

 of which it is quite distinct. Material is at hand from the follow- 

 ing localities :
