Microdiplodia laurina Dearness & House, sp. nov. 



Pycnidia scattered, intra cortical, covered by the adherent cuticle 

 which ruptures in a narrow cleft, globose, dark brown, about .3 mm 

 in diameter. 



Conidia brown, i-septate, oblong-elliptic, 9-12 by 3^-5 ju. 



On dead branchlets of Sassafras variifolium (Salisb.) . 

 Kuntze, Sylvan Beach, Oneida county, N. Y. H. D. House, May 

 191 5. Also collected on same host at Albany, N. Y., November 19 15. 



Very distinct from Microdiplodia sassafras (Tracy & 

 Earle) where a subhyaline septum divides the spores unequally. 



Mollisia plicata (Rehm.) Sacc. 

 var. baptisiae Dearness & House, var. nov. 

 Asci 40-45 X 5-6 ii; paraphyses linear, thickened at the apex; 

 spores i-celled, about 6-8 x 2-2 1 ju.

 Hotise, November 25, 191 5. 



Phoma ochra Cooke 



On dead stems of Hibiscus moscheutos L. Oceanside, 

 N. Y. H. D. House, July 28, 1916. The spore measurements are 

 nearest those given for Phoma malvacearum West., but 

 other characters seem to relate it more closely to P. ochra, from 

 which it differs only in having smaller spores (7x3 n), instead of 

 10-12 X3§-4 ju. 



The same specimens contain an interesting Diaporthe which 

 seems referable to D, a r c t i i Lasch.

 count3^ H. D. House, April 10, 1916.

 blackening the stems when erumpent, subcuticular at first then 

 breaking through longitudinal clefts in the epidermis; ostiola round, 

 black, shining; conidia hyaline, minute, oblong, straight or curved, 

 5 x 1.5-2 /i.
