 immediate vicinity of the Arciiaria locality. The " new court

 though it has recently been moved aside and superseded b)' a 

 modern brick structure.

SHORTER NOTES 



A New Polvporoid Genus from South America. — An inter- 

 esting pore-fungus was collected a few years ago in Colombia b)' 

 Mr. C. F. Baker. It is the only species of Polyporaceae known 

 to me which occurs parasitic on living leaves. I have erected 

 upon it the new genus Pliylloporia, a description of which follows : 



Phylloporia gen. nov. 



Hymenophore small, tough, annual, attached by the vertex to 

 the lower surface of living leaves; context brown, fibrous, tubes 

 thin-walled, mouths polygonal ; spores globose, smooth, pale 

 ferruginous. 



The distinguishing feature of this genus is its habit of growing 

 upon living leaves. It is based upon the following species : 



Phylloporia parasitica sp. nov. 



Pilcus circular, thin, attached by its vertex to the under surface 

 of li\ing leaves, 5-8 mm. in diameter, 0.2—1 mm. thick; surface 

 minutely tomentose, fulvous, margin thin, entire, ochraceous to 

 ferruginous ; context membranaceous, fibrous, ferruginous ; tubes 

 0.5 mm. or less in length, -^-"j to a millimeter, isabelline, polyg- 

 onal, irregular, edges thin, entire to coarsely dentate ; spores 

 globose, smooth, very pale ferruginous, 3—4 il, hyphae con- 

 colorous. 



Collected by C. F. Baker near Bonda, Colombia, Nov. 16, 

 1898, on living leaves of Bigiioiiia (?). Numerous sporophores 

 in various stages of development are found on the lower surface 

 of the leaf, usualK* attached to a vein. This species is the only 

 one of its faniih- in America that occurs on livincr leaves.
