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, 

 at first hyaline, becoming dark brown, 12-16 X lo-ii mic. 



On old fungi (Polyporus). 



Type locality : Europe.
