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.
