 Burt, Mo. Bot. Gard. Ann. 3: 323. 1916. 



Type : in Museum of Paris. 



Since my account of this species I have studied specimens of 

 both the Cuban collections distributed by C. Wright under the 

 name Thelephora pedicellata and find that the collection, C. 

 Wright, 798, distributed in Wright, ' Fungi Cubenses Wrightiani ' 

 is in condition to afford the structural details figured by Patouil- 

 lard and therefore must be the type distribution of his species. 



The general description of this species, which could not be 

 given before, is: 



Fructifications resupinate, dry, avellaneous, pulverulent, oc- 

 curring in small, interrupted patches, each about 2-3 mm. in 

 diameter; in structure 500-600 tx thick, colored, stratose, com- 

 posed of 2 strata, each consisting of a hymenial crust supported 

 on pillars or pedicels about 15 [x in diameter, with their com- 

 ponent hyphae about 3 ^l in diameter; probasidia borne at the 

 surface of the hymenial layer. 



On living bushes among, and on, mosses and lichens. Cuba.
