S. rufum may be recognized at sight by its occurrence on 

 prostrate poplar limbs and logs in the form of small vinaceous 

 fructifications with the hymenium gyrosely wrinkled. The 

 fructifications become peltate when full grown, attached by the 

 center, and with the marginal portions free and turned outward.
