748 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



States in Alabama, Idaho, and Oregon only. I am greatly in- 

 debted to Mr. L. Romell for a preparation from the type of 

 Radidum spinulosum which makes possible the reference to 

 this species. 



Specimens examined : 

 Sweden : Stockholm, L. Romell, 327, and three unnumbered 



collections. 

 Alabama : Peters, Curtis Herb., 4543, preparation from type 



(in Kew Herb.). 



Idaho: Kaniksu National Forest, Priest River, J. R. Weir, 

 55. 



Oregon : Eugene, C. J. Humphrey, 1103. 



5. E. gelatinosa Murrill, n. sp. Plate 27, fig. 12. 



Type : in N. Y. Bot. Gard. Herb, and in Burt Herb. 



Fructification coriaceous, effuso-reflexed, white when young, 

 finally clay-colored, tomentose, soft to the touch, margin 

 obtuse; context soft, spongy, zonate; hymenium tough, gela- 

 tinous, drying Hay's bro^vn, even; basidia longitudinally 

 septate, 13 X H m; spores simple, colorless, even, flattened 

 on one side, 8-10 X 6 /x. 



Eeflexed portion of fructification 1^2 cm. long, 2^ cm. wide, 

 ^ cm. thick. 



On rotting wood in wet, wooded regions. Jamaica. Decem- 

 ber and January. 



Only two collections of one fructification each were made. 

 That of December 17 is a w^hite, young specimen, with no 

 basidia developed, which shows the general habit and early 

 characters of the species, but would not have been determin- 

 able except for the later collection of January 12-14, which 

 shows the darker coloration assumed at maturity. The thick, 

 spongy, soft pileus of the mature fructification distinguishes 

 this species from others known at present. 



Specimens examined: 

 Jamaica : Troy and Tyre, Cockpit country, W. A. Murrill S 



W. Harris, N. Y. Bot. Gard., Fungi of Jamaica, 1087, type 



(in N. Y. Bot. Gard. Herb.), a portion in Burt Herb.; Blue
