Murrill: Light-colored Resupinate Polypores 97 



very strong odor in drying ; pores nearly round or subangular, 

 2-3 mm. long, resting on a separable substratum or membrane, 

 which is of a soft, carnose nature, not very tough and about 1 

 mm. thick. The hymenium is stratose. 



The range of this species is remarkable, as will be seen by ex- 

 amining the list of collections below. Among its hosts are apple, 

 linden, red maple, ash, Alnus rhombifolia, old hymenophores of 

 Hapalopilns gilvus, pine, and Pinus radiata.

Described as follows from specimens collected by Peck on 

 chestnut wood at Selkirk, New York, in August : 



" Resupinate, rather thick, tough, following the inequalities of 

 the wood ; pores minute, rotund, short, buff-yellow or cream 

 color, becoming dingy red or dull incarnate where wounded, the 

 subiculum fibrous, changing color like the pores, the whole plant 

 assuming an incarnate hue when dried." 



There are also specimens at Albany collected at Croghan, Bol- 

 ton, and Savannah, New York ; and I have six specimens col- 

 lected on chestnut elsewhere, three from Connecticut, one from 

 New Jersey, one from Pennsylvania, and one from Canada. The 

 other specimens listed below may also be from chestnut, but the 

 host is not mentioned in any case.
