Pileus purplish and waxlike when fresh, one-eighth to nearly one- 

 half inch broad. Coryne urnalis (Nyl.) Sacc. has been 

 collected by Doctor Peck at North Elba. 



Coryneum pithoideum Dearness & House, sp. nov. 



Acervuli in lenticel-like pustules thinly but regiolarly scattered, 

 producing circular ruptures of the epidermis and contiguous cortex, 

 1-1.5 mm in diameter, seated in the cortex, not compact, of the size 

 of the crateriform rupture, often appearing under the lens as if 

 caespitose. 



Conidia cask-shaped, variable in size, averaging about 25 by 12 n, 

 mostly 5 -septate, brown with a hyaline cell at each end. 



On dead stems of Celastrus scandens Linn., Kenwood 

 swamp near Oneida, N. Y. H. D. House, May 15, 1915. Type in 

 the herbariiun of the New York State Museiim. 



This has the naked eye appearance of Coryneum pustula- 

 t u m Peck, described on dead branches of oak and chestnut, but 

 the spores are more nearly like those of Coryneum compac- 

 tum B. & Br. 



Cryptospora leiphaemoides Dearness & House, sp. nov. 



Stromata scattered, raising the perforated epidermis and black- 

 ening the underlying cortical pustule, 1-1.5 mm; the disc .2 5-.3 

 mm, whitish at first, but becoming granular and darker when the 

 very short, black ostiola appear thru it. 



Perithecia 5 to 8 in a stroma, pale gray, h'ing in the unaltered 

 cortex and in transection strongly resembling Diaporthe 

 leiphaemia (Fr.) . 



Asci clavate-cylindrical, paraphysate, 65-go ^t, mostly about 

 75 X 10 /x. Sporidia parallel in the asci, cylindrical, subarcuate, 

 subclavate, continuous, pluri-guttulate, 25-60 n long, mostly about 

 45 /i, upper half 4-5 fx in the thickest part, lower half 2.5-3 M- 



On dead twigs of Quercus alba L. Astor woods, near 

 Bronx Park, New York City. H. D. House, April 24, 1916. Type 

 in the herbarium of the New York State Museum. 



Externally the stroma and disc of this species resemble Cry p- 

 tospora albofusca (C. & E.), also on Quercus, but it differs 

 decidedly in its sporidia and paraphyses as represented in F. Col. 36 

 (material of Mr Ellis's collection). C. albofusca is described 

 in the section Eucryptospora but in F. Col. 36 the sporidia are 

 3 -septate in the copy examined.
