Its size and habit of circinating between the epidermis and cortex 

 presumably led Doctor Peck to call it Melanconiella de- 

 coraensis. Mr Ellis remarked upon the greenish, pulverulent 

 stroma and called it variety subviridis Peck, although in the place 

 cited by Ellis, Doctor Peck did not publish any such varietal name, 

 nor elsewhere. In addition to the other differences are the lack of 

 a disk, the larger asci and spores, and the marked differences in 

 size and shape of the conidial stage. 



Xylaria Castorea Berk. 



Newcomb, Essex county. H. D. House, September 20, 1922. 

 Hulett's Landing, Lake George. Madge Dearness Tamhlyn, Sep- 

 tember I, 191 5. 



The type of Xylaria Castorea Berk, was collected in 

 New Zealand, but Morgan sent to M. C. Cooke specimens from 

 Ohio which Cooke identified as this species. J. B. Ellis wrote a 

 description of the Morgan specimens^^ which agrees with the New 

 York material. Lloyd is disposed to regard it as a variet}- of 

 Xylaria polymorpha. Doctor Peck collected it at Low- 

 ville, Lewis county, and described it as Xylaria corniformis 

 i r r e gsu 1 a r i s .^'' Subsequently he made additional collections at 

 Floodwood, Ampersand pond and North Elba, which he identified 

 as Xylaria Castorea, ^^ and also changed the name of 

 "irregularis" on his herbarium specimens to "Castorea."
