REPORT OF THE STATE BOTANIST, I919 37 



July 17, 1 91 8. H. D. House. Also collected on same host at North 

 Greenbush, several years ago by Doctor Peck, the material somewhat 

 immature. Obviously related to but differing in several characters 

 from Leptosphaeria acuta (Moug. ) Karst. 



Leptostromella scirpina Peck 



On dead leaves of Scirpus cyperinus (L.) Kunth. Pecks- 

 j>ort, Madison county, May i8, 1918. H. D. House. Originally 

 described from Nebraska on Scirpus atrovirens. . 



The Pecksport material is referred here although there are minor 

 differences. In some of the pycnidia the spores are obtuse at one 

 end and average under 19 micr. in length, but in others they are 

 acute at both ends and reach 25 micr. in length. As a rule these 

 are more orbicular than in the type material collected in Nebraska. 



Leptothyrium conspicuum Dearness & House, sp. nov. 



Spots reddish brown, irregular, 4 to 25 mm, in some instances 

 extending over the whole leaf, darker above, the small spots defi- 

 nitely limited by a raised reddish border which disappears with the 

 extension of the spot over the leaf. Pycnidia amphigenous, black, 

 gregarious near the center of the spot or scattered over the whole 

 area, circular, flat, subcuticular, becoming somewhat erumpent, 

 rugose, .2 to .3 mm in diameter; conidia hyaline, 3.5-4 x i /a, on short 

 basidia. 



On living and languishing leaves of Vaccinium vaciUans 

 Kalm, near New London, Oneida county, July 20 and August 27,
