Dial one ctria fulvida Ellis & Everh. Jour. Myc. 2: 136. 1886. 

 Ophionectria Everhartii Ellis & Galw. Jour. Myc. 6: 32. 1890. 



Perithecia gregarious, nearly globose, dull yellow becoming 

 darker with age, more or less rough and furfuraceous externally, 

 or with a few hair-like outgrowths, with a papilliform ostiolum, 

 150-175 mic. in diameter; asci cylindrical, 8-spored, 65-80 X 

 8-12 mic. ; spores varying from fusiform to cylindrical or clavate, 

 straight or curved, with the ends usually acute, hyaline or very 

 pale yellow, 7-10-septate, 35-50 X 3—3.5 mic. ; paraphyses short, 

 indistinct. 



On old fungi, especially Diatrype. 

 Type locality: S. Carolina. 



Distribution : Newfoundland and Ontario to S. Carolina. 



Illustration : Ellis & Everh. N. Am. Pyrenom. pi. 15. /. 1-3. 



Specimens examined: Newfoundland, Waghorne 755; 

 Ontario, Dearness 2292; New Jersey, Ellis (type of D; fulvida 

 and O. Everhartii) . 



Distinguished by the globose, slightly furfuraceous perithecia 

 and by the habitat. 



2. Ophionectria cylindrothecia sp. nov. 



Perithecia gregarious or scattered, cylindrical to clavate or 

 fusoid, tapering below into a stem-like base, also tapering above, 

 yellowish, translucent, nearly smooth, rather hard when dry, 

 often with a few septate, hair-like mycelial strands near the base, 

 naked above, 125-150 X 275-300 mic; asci cylindrical or clavate, 

 8-spored, 100-125 X 12-15 mic; spores apparently enclosed in a 

 separate membrane within the ascus, so that the outer wall of the 

 ascus stretches 10-20 mic. beyond the apex of the spore cluster; 

 individual spores tapering toward either end, hyaline or very 

 slightly yellowish, 7-12-septate, 60-75 X 5 mic ; paraphyses 

 present, indistinct (pL 4. f. 4). 



On old corn stalks, Zea Mays. 



Type locality: Ohio. 



Distribution : Known only from type locality. 

 Ohio, Morgan 1007 (type). 



Distinguished by the elongated perithecia and the large size 

 of the asci and spores as well as by the habitat.
