Erom the articulated creeping mycelium, spring slender, 

 very minutely scabrous threads, branched proliferously ; 

 ramuli often alternate, attenuated, their apices swelling into 

 a pyriform, 4-5-lobed receptacle, from which spring elliptic 

 spores, some of which are echinulate, others smooth, with 

 two nuclei. The lobes are not mamillate, as in S. atra, and 

 the spores have no true septum. (Berk.)
