GEASTER. 163 



Genus V. GBASTBR. Midi. Earth Stars. 



Peridium globose, consists of two coats ; outer coats splitting 

 at the apex downward, into several segments, which become 

 reflexed in a stellate form ; inner peridium thin, membrana- 

 ceous then papyraceous, sessile or with a short pedicel. 



Capillitium takes its origin from the inner surface of the 

 peridium, also a distinct columella. Threads simple, slender ; 

 spores small, globose.
