Apothecia thickly scattered, occurring singly, or two or three 

 together, rounded, becoming more or less turbinate, subochra- 

 ceous, reaching a diameter of .25-. 5 mm.; hymcnium at first 

 concave, becoming plane, similar in color to the outside of the 

 apothecium; asci broad-clavate, 8-spored, reaching a length of 

 90 ju and a diameter of 20-22 /x; spores broad-ellipsoid, granular 

 within, 10-12 X 20-25 ju; paraphyses filiform, slender. 



On Viburnum lantanoides. 



Type locality: Catskill Mountains, New York. 



Distribution: New York and Ontario, Canada. 



Specimens in the herbarium of The New York Botanical 

 Garden, a part of the type collection, have been examined. In 

 this material it is very difficult to find mature spores. Whether 

 they become septate could not be determined. 



One specimen collected by Roy Cain, in Canada, No. 7162, 

 has been compared with the type and found identical.

 Res. 17: 140. 1939. (Plate 146.) 



Conidial fruiting bodies minute, about .3-. 4 mm. in diameter, 

 erumpent, cushion-shaped, and containing one or more cavities 

 lined with conidiophores 2.5-3 X 15-30 /x> swollen just below the 

 point of attachment to 4 yu; conidia oblong-ellipsoid, hyaline, 

 simple, straight, or slightly curved, 12-14 X 30-45 ju; micro- 

 conidia borne in the same fruiting body, hyaline, filiform, straight, 

 or curved, simple, 1.5-2 X 10 18 ix. 



Apothecia erumpent, scattered, or more or less in rows, 

 usually single, sometimes cespitose with two to six in a cluster, 

 sessile, narrowed below, circular .3-1 mm. in diameter .2-.4 mm. 

 high, pale ochraceous-yellowish, darker when dry, waxy; hy- 

 menium plane to convex, slightly pruinose; asci oblong-clavate, 

 broad, short-stalked, 8-spored, reaching a length of 90-120 ix 

 and diameter of 20-30 /x; ascospores oblong-ellipsoid to ovoid, 

 hyaline, straight, or curved, irregularly 2-seriate, becoming 1-3-
