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.
