Usually hypophyllous, very rarely amphigenous ; mycelium 

 often ev^anescent, but sometimes more or less persistent, and then 

 thin and effused, or rarely forming definite patches ; perithecia 

 usually scattered, but sometimes gregarious, large, globose-de- 

 pressed to lenticular, 140-270 fi in diameter, or rarely reaching to 

 350 a in diameter, cells rather obscure, 15-20 // wide, apex of 

 perithecium provided with a mass of densely crowded special out- 

 growths from the external cells, each outgrowth when mature ter- 

 minating in a fascicled head of numerous short hyphal branches, 

 which, when the perithecium becomes turned over, grow more or 

 less mucilaginous and fix the perithecium upside down to the 

 substratum; true appendages equatorial, usually from 5—18, oc- 

 casionally as many as 25, 1-3 times the diameter of the perithe- 

 cium, acicular, rigid, straight or occasionally slightly flexuose 

 towards the apex, aseptate, colorless or very rarely yellowish- 

 brown at the apex, swollen at the base into a hollow bulb ; asci 

 5-45^ subcylindrical to ovate-oblong, 60- 105 x 25-40 /i, very 

 rarely as large as 120 x 50 /i, more or less stalked; spores 2, 

 rarely 3 (4 recorded by some authors), variable in size, sometimes 

 curved or rather irregular in shape and larger at one end than at 

 the other, 30-42 a, rarely reaching to 50 /^, x 16-25 /A ^vhen 3, 

 smaller^ about 24 x 14 «.
