Phoma ailanthi Saccardo. 



On dead shoots of A i 1 a n t h ti s glandulosus Desf.

Phoma imperialis Sacc. & Roum. 



(Phoma paulowniae Sacc. not Thi'uu.) 



On twigs of P a u 1 o w n i a tomentosa (Thunb.) Baill. 

 Yonkers, N. Y. H. D. House, May 8, 191 5. 



The typical species inhabits petioles of P a u 1 o w n i a imperi- 

 alis in France. The description in the Sylloge is rather meager to 

 establish positively the identity of the Yonkers material, but for 

 the nonessential fact that the former was on petioles while ours 

 inhabits twigs, there is no difference so far as the description of the 

 type goes. The following description is drawn from the Yonkers 

 material. 



Pycnidia immersed in the thin bark, mostly elliptic, i x .25-.3 mm, 

 flat, dark brown or black and showing through the epidermis which 

 is pierced by the short conic stomata ; conidia abundant, hyaline, 

 somewhat acutely elliptic, nucleate, 6-9 x 3 /x on basidia of about 

 their own length. 



Phoma paulowniae Thiim. is quite distinct. 



Phoma linariae Dearness & House, sp. nov. 

 Pycnidia dark brown, very numerous, flat to subglobose or 

 depressed aroun-d the small central stomata which pierce the cuticle, 

 150-200 /x in diameter; conidia numerous, hyaline, oblong to some- 

 what curved, 2-3 x i yu.
