Original description. 



T. aurantium differs from the preceding species of Tre- 

 mellodendron hj its simple fructifications. I have seen no 

 specimens referable here. Professor Atkinson had intended 

 to make a negative from his type so that I could include a 

 figure of the species, but, upon going to the envelopes labelled 

 T. aurantium, he found that they contained ^by error of a 

 helper T. merismatoides instead. The specimens of T, 

 aurantium have not been found. 



7. T. simplex Burt, n. sp. Plate 26, fig. 5. 

 Type : in Mo. Bot. Gard. Herb, and in Farlow Herb. 

 Fructifications scattered, erect or suberect, drying hard, 



brittle, somewhat longitudinally wrinkled and sometimes com- 

 pressed, black above, olive-ocher with the hymenium towards 

 the base; hymenium amphigenous on the lower third of the 

 fructification, olive-ocher, hyaline under the microscope, with 

 surface consisting of colorless clavate paraphyses 5 ii thick.
