Apothecia scattered, sessile, globose when young, becoming 

 expanded and subdiscoid, reaching a diameter of 2-3 mm.,

 surface, convex, dark-brown ; asci subcylindric to clavate, taper- 

 ing below into a long stem-like base, strongly protruding at 

 maturity and appearing in dried specimens as minute, whitish 

 granules over the surface of the hymenium; spores at first 2- 

 seriate or irregularly bunched near the apex of the ascus, gradually 

 separating, finally becoming 1-seriate, at first smooth and 

 surrounded by a hyaline band, gradually becoming sculptured, 

 reaching a diameter of 30-35 jj. including the spines; spore- 

 sculpturing assuming the form of reticulations which are often 

 more or less indistinct or broken, at maturity echino-reticulate,
