 338 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



On bark of living limbs of frondose species. Mexico, West 

 Indies, and Venezuela. February, March, November; spore- 

 bearing in November. 



This species is highly distinguished by honey-yellow color 

 and the division of its fructification into narrow, sinuous, 

 branched divisions, resembling those of the thallus of the 

 lichens, Physcia stellaris and P. ohscura. Spore-bear- 

 ing organs are not abundant in the only fertile specimen 

 which I have seen. They appear to become somewhat cork- 

 screw-shaped, with no indication of bearing spores except on 

 the terminal cell, but I was not certain on this point because 

 the occasional attached spores were along the edge of thick 

 sections where only the apex of the organ extended beyond 

 the paraphyses. In two cases probasidia were bearing at 

 the apex, each a body of the form and dimensions of a spore 

 of this species. In the deeper portions of the fructifications 

 brown, pyriform bodies of the same size and form as the 

 probasidia are borne by the hyphae in the same location 

 as the probasidia. These brown organs are often of the same 

 dimensions as the spore-bearing organs, septate, and gorged 

 with brown contents.
