From July to December, 1898, tufts five inches in diameter grew 

 from an oak stump close by the writer's cottage at Mt. Gretna, Pa. 

 These tufts dried, and revived after rain into a gelatinous condition. 

 They were nibbled at raw, and several were cooked. Tufts were found 

 elsewhere in the same woods and eaten by others. They were unani- 

 mously approved. The species dries hard, like thin glue, but is darker. 

 A dried piece swells in the mouth, grows tough, and has but little taste. 

 Flavor develops in cooking.
