1. Septobasidium pedicellatum Patouillard, Jour, de Bot. 

 6:61. textf. 1892. 



Thelephora pedicellata of C. Wright's Cuban Exsiccati, 

 but not of Schweinitz. 



Type: in Museum of Paris. 



Fructification with pillars or pedicels composed of hyphae 

 which branch towards the upper end and pass into and sup- 

 port the hymenial crust ; probasidia subglobose, 20 X 15-20/*, 

 arising as lateral outgrowths near the ends of the final 

 branches of the hyphae, producing from the apex a hyaline, 

 cylindric, spore-bearing organ, 35 X lOy-t, 2-3-septate, which 

 becomes horseshoe-shaped, slightly constricted at the septa, 

 and has a small protruberance on the convex side of each 

 cell; no spores seen. 



The above is a summary of the account by Patouillard,^ 

 of the structure of the specimen in the Museum of Paris, 

 collected in Cuba by C. Wright and distributed by him in 

 his Cuban exsiccati under the name Thelephora pedicellata, 

 Wright made two collections in Cuba which were determined 

 by Berkeley and Curtis^ as Thelephora pedicellata. Since 

 Patouillard omitted the data on the label of the specimen 

 which he studied, I do not know now which of Wright's 

 numbers is the type collection and have to defer a fuller 

 consideration of this species to the supplement to my mono- 

 graph.
