Perithecia gregarious, seated on a more or less well developed 

 subiculum consisting of a black mycelial growth, ovate to pyri- 

 form, black, roughened and abundantly clothed with hairs ; hairs 

 black to the unaided eye, very dark brown with the microscope, 

 long and flexuose near the base and shorter and more or less 

 rigid above, blunt or subacute, simple or sparingly septate, the 

 shorter hairs about 50-80 /x, in length and 6 fx in diameter, quite 

 variable in length ; substance of the perithecium tough, black and 

 opaque ; asci cylindric or clavate, 8-spored ; spores 2-seriate or 

 irregularly crowded, long vermiform, often abruptly curved near 

 one end, hyaline, becoming pale brown with 8-10 large distinct 

 oil-drops, for a long time simple, finally becoming delicately 

 6-7-septate, usually with one septum between each two oil-drops, 

 50-80 X 6-8 /X (PL 2, f. 1-7).
