Quotation. — A Pol\'pore on a leaf we would never expect, but per- 

 haps there is something new under the sun. We quote from W. A. Mur- 

 rill in Torreya : 



"A New Polyporoid Genus from South America. — An interesting 

 pore-fungus was collected a few years ago in Columbia by Mr. C. F. Baker. 

 It is the only species of Polyporaceae known to me which occurs parasit- 

 ic on living leaves. I have erected upon it the new genus Phylloporia, a 

 description of which follows : 



"Phylloporia gen. nov. Hymenophore small, tough, annual, attached 

 by the vertex to the lower surface of living lea\ es ; context brown, fibrous, 

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

 ru gin bus. 



"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. Pileus circular, thin, attached by its 

 vertex to the under surface of living leaves, o-S nun. in diaemter, ()-2-lmm. 

 thick; surface minutely tomentose, fulvous, margin thin, entire, ochraceous 

 to ferruginous; context membranaceous, fibrous, ferruginous; tubes 0.5 

 mm. or less in length, 3-7 to a millimeter, isabelline, polygonal, irregular, 

 edges thin, entire or coarsely dentate ; spores globose, smooth, very pale 

 ferruginous, 3-4 m; hyphae concolorous. ^' 



"Collected by C. F. Baker near Bonda, Colombia, Nov. 16, 1S9S, on 

 living leaves of Bignonia (?). Numerous sporophores in various stages 

 of development are found on the lower surface of die leaf, usually attached 

 to a vein. This species is the only one of its family in America that occurs 

 on living leaves. Looked at fron'. above, the host appears to be attacked 

 by a leaf-parasite and it is quite surprising to find on the lower surface 

 the snorophores of one of the Polyporaceae." [William Alphonso Mur- 

 rill, Torreya].
