Gregarious, erumpent, sessile but attached by a narrow 

 central point, at first subglobose and closed, soon expanding 

 and becoming patellate, plane or slightly convex, often more 

 or less marginate, 1-1 * 5 mm. across, entirely orange-brown 

 and minutely pulverulent ; excipulum dingy orange, con- 

 sisting of parallel rows of septate hyphae that become 

 clavate, septate, and free from each other at the circum- 

 ference, the terminal subglobose cells are sometimes studded 

 with minute particles of lime ; asci clavate or sometimes 

 cylindrical, and narrowed abruptly into a short pedicel, wall 

 thick, 8-spored ; spores irregularly 2-seriate, elliptic-oblong 

 or fusoid, straight or slightly curved, hyaline, often guttu- 

 late and with granular contents, smooth, for a long time 

 continuous, finally 3-septate, 18-25 X 6-7 fx; paraphyses 

 filiform, septate, tips clavate, coloured orange-brown, up to 

 6 jx thick ; gradually passing into the structure of the
