Sphaerocarpus antiadcs, Bull., Champ., p. 1 27, t. 368. 



Trichia antiadcs, D.C., Fl. Fr., 2, p. 252 ; Chev., Par., p. 325. 



On rotten wood. France. 



Stem thick, deformed, several confluent, branched, irregularly 

 lacunose ; hypothallus membranaceous, whitish ; sporangia de- 

 hiscing by irregular rupture towards the apex from which the 

 capillitium protrudes. (Fr.) 



Judging from Bulliard's figure, and also from some points in 

 the description, the present species is much more likely to be 

 a Cribraria than a Physarum.
