 a permanent character. 



The color of the young lamellae is not known. The mycelium 

 binds together a mass of sand at the base of the stem. This ad- 

 heres to the stem when carefully taken up and gives it the ap-

 species may very appropriately commemorate the name of the 

 illustrious botanist, C. E. Bessey, who with his son, E. A. Bessey, 

 discovered it.
