Perithecia scattered or gregarious, nearly globose, sparingly 

 clothed with pale brown hairs, 400-500 mic. in diameter, with a 

 beak, 1-2 mm. long and 100 mic. in diameter, tip of beak clothed 

 with hyaline hairs, entire perithecium at maturity black ; asci 

 broad-clavate, 35-40X12-15 mic; spores elliptical or fusoid,
