Gnomoniopsis acerophila Dearness & House, sp. nov. 



Perithecia under and entirely covered by the epidermis except the 

 subulate ostiola, not at all or but slightly raising the cuticle ; depressed 

 globose, curling-stone shaped, .6 to .8 mm in diameter ; ostiola 

 acuminate, .75 to i mm long, the tip hyaline for a distance of 180 to 

 200 micr. Asci lacking paraphyses, rather variable in shape, from 

 that of a wide short sheaf to long cyhndric, 33 x 23 /x to 90x8/x, 

 niostly obliquely saccate. Sporidia hyaline, parallel-congregate to 

 biseriate, mostly 3 to 5 in the upper part of the ascus and over- 

 lapping the others in the lower half, 1-5 septate, 24-30 x 3 1 2-4 jn. 



On petioles of fallen leaves of the striped maple, Acer penn- 

 sylvanicum L. Oneida, Madison county. May 15, 1918. H. D. 

 House. Type in the New York State Museum herbarium. 



Hendersonia linderae Sacc. 



On dead branches of the spicebush. Benzoin aestivale 

 (L.) Nees. Oneida, Madison county, May 15, 1918. H. D. House. 

 The same collection contains in addition to the Hendersonia, 

 two species of D i p 1 o d i a , namely, Diplodia linderae 

 E. & E., and the other possibly Diplodia insitiva Sacc. Sac- 

 cardo in publishing the latter did not give the measurements and 

 although cotype material is available for comparison, it is a mixed lot 

 and one can not be sure just what was described by Saccardo. There 

 was also present a little material of Valsaria insitiva var. 



Hypoxylon transversum ( Schw. ) Sacc. 

 On dead limbs of yellow birch, Betula lutea Michx.f. 

 Chittenango Falls, Madison county, May 17, 1918. H. D. House.

Perithecia scattered, gradually blackening the stems, covered by 

 the cuticle, finally bare, globose-conic, rugose, papillate, 270 to 350 

 micr. in diameter ; ostiola cylindrical, merely piercing the cuticle. 

 Asci terete, short-stipitate, 60-105 /i, mostly about 75X lO/x; para- 

 physes linear, longer than the asci. Sporidia amber colored, biseriate, 

 straight or nearly so, widest in the middle, riot constricted at the 

 septa, gradually narrowing to the subacute ends, 5-8-septate, mostly 

 6-nucleate, 28-35, mostly 30-32 x 4 /x.

 Collinsonia canadensis L. Oneida, Madison county.
