Gregarious or sometimes confluent, sessile, subgelatinous, 

 closed at first and almost globose, then becoming plane with 

 a blunt, glabrous, upraised margin, surrounded by a delicate 

 web of hyaline, septate, branched hyphae, which spring from 

 the basal cortical cells, clear orange, §— 1^ mm. across ; ding}- 

 orange, but almost unchanged in form when dry; hypothecium 

 and excijmluru truly parenchymatous, cells large, cortical 

 cells irregular in form and size, up to 20 /jl across, becoming 

 smaller towards the entire margin ; asci narrowly clavate, 

 8-spored ; spores obliquely 1 -seriate, hyaline, continuous, 

 straight, 5-6 X 1 * 5 \x ; paraphyses numerous, cylindrical, 

 2-5 fx thick, slightly flattened and broadened like the head
