 Ophionectria Evcrhartii 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. pL i^. f. i-j. 



Specimens examined: Newfoundland, Waghorne y^j; 

 Ontario, Dearness 220)2; New Jersey, Ellis (type of D. fulvida 

 and 0. 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 verv 

 slightly yellowish, 7-12-septate, 60-75X5 mic; paraphyses 

 present, indistinct (pi. 7. /. //). 



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.
