'Perithecia immersed, obtusely papillate and at length subpromi- 

 iiei it. 200-225 tj. diam. Asci cylindrical, 56x4 p. Sporidia clicly- 

 uious, upper cell globose (4 //.), lower cell subovate, 4x 3 /*, hyaline." 



Spccc. on bark of decaying (maple?) limb on the ground, New- 

 field, N. J., have (stroma?) 2 cm. hiirh. clavate, leather-color. Only 

 two specimens were found, and those were immature, so that the fruc- 

 tification could not be made out, though the surface of the club was 

 finely punctate from the ostlola of the immersed perithecia. Accord- 

 ing to Tulasno & Broome, the club-shaped body, on the upper part of 

 which the perithecia are borne, is not a true stroma, but either 

 Clavaria Ityula or Spathularia fl<ir/<l<i bearing the Hypocrea as a 

 parasite.
