Dating below the bark and appearing at first as a long, 

 straight, or curved, convex ridge, then rupturing the bark, 

 which forms two irregularly torn, spurious lips ; black at 

 first, then gradually opening by an elongated slit, the lips 

 often pale in colour ; lips at length widely open, exposing 

 the pallid disc; up to 1-5 cm. long by 1-5-2 mm. wide, 

 straight or curved ; asci clavate, apex narrowed, continued 

 downwards into a long, slender pedicel, spores 8, arranged 

 in a parallel fascicle, needle-shaped, as long as the swollen 

 part of the ascus, about 95 x 1'5 ju, hyaline, at first multi- 

 guttulate, then multi-septate; paraphyses filiform, equal, 

 about 1 • 5-2 /a thick, colourless, not thickened at the more 

 or less curled apex, longer than the asci.

 1-5, p. 91. 



On small branches and twigs of oak. 



Distinguished by the large ascophores growing more or 

 less transversely on the young branches, and looking like 

 gaping cracks when expanded. 



Colpoma degenerans. Mass. (fig. 51, p. 22.) 



Gregarious, erumpent, the ruptured bark forming spurious 

 lips, sessile, roundish then elongated, disc almost plane, 

 blackish-brown or livid, soft, 1-3 x 1 mm. ; asci clavate 

 apex slightly narrowed, base attenuated into a long, slender 

 pedicel, 8-spored; spores filiformly clavate, straight, hyaline, 

 continuous, 85-95 X 2*5 //, arranged in a parallel fascicle; 

 paraphyses slenderly cylindrical, about 2 ^ thick, colour- 

 less.

On dead branches of Vacciniiim. 



A variable species, but distinguished by the very slender, 

 elongated, continuous spores, which, from a needle-like base 

 become gradually thickened upwards, increasing about 3 fx. 

 thick at the apex, thus resembling a very long, slender 

 club. Ascophore usually more or less elongated, sometimes 

 roundish, at first bordered with the upraised torn bark, 

 proper margin almost obsolete ; disc almost or quite plane.
