6. Coriolus subluteus (Ell. & Ev.) 



Polyporus subluteus Ell. & Ev. Am. Nat. 31 : 339. 1897. 



Described from plants collected by Dearness on old beech 

 trunks in Canada as follows : 



'.'Effused; pileus white, with short tomentum, azonate, subimbricate, margin ob- 

 tuse, context soft and flexible, upper margin more or less reflexed ; pores subcolliculose, 

 unequal, round or subsinuous, J/j-^ mm. in diameter, %-l cm. long, subluteous when 

 dry, white inside, margin subdentate, dissepiments thin, context white, not fibrous ; 

 spores oblong, very slightly pointed, white, 4-6 X I.J^-2 //." 



The type collection of this species is now in the herbarium of 



the New York Botanical Garden. Too little is known of the 



plant to be sure that it is not an overgrown resupinate form of some 



other species. 



7. Coriolus Sartwellii (B. & C.) 



Polyporus Sartwellii B. & C. Grevillea 1 : 51. 1872. 



Described from plants collected on trunks in New York by 

 Sartwell. Specimens from New England collected by Sprague 

 were also at hand. There is in the Ellis collection a box of plants 

 collected at Potsdam, New York, in January, 1861, which agree 

 perfectly with the types of P. Sartwellii now at Kew. These 

 plants grew on hemlock logs. Specimens collected by Under- 

 wood on pine at Centerville, New York, in April, 1887, appear to 

 be specifically identical and show the hymenium to be yellowish 

 instead of black, as in the description, becoming dull-brown with 

 age. Nothing further is known of the species unless Leveille's 

 brief description of Polyporus subjlavus (Ann. Sci. Nat. Bot. III. 

 5 : 300. 1846), collected on trunks in New York by Salle, refers 

 to the same plant ; and this is quite improbable. 



8. Coriolus brachypus (Lev.) 



Polyporus brachypus Lev. Ann. Sci. Nat. Bot. III. 5 : 127. 1846. 

 Polyporus albo-cervinus Berk. Hook. Jour. Bot. 8 : 234. 1856. 

 Coriolus albo-cervinus Pat. Tax. Hymen. 94. 1900. 



This species was first described from plants collected on trunks 

 in Guadeloupe by L'Herminier. Berkeley's name was assigned to 

 specimens from Panure, Brazil, collected by Spruce. He remarks
