REPORT OF THE STATE BOTANIST I917 87 



Notes. The original packet is now preserved in a herbarium 

 box at Albany. It contains a single specimen that measures 7 cm 

 long by about 3 cm broad, a photograph of which is reproduced on 

 plate 8, figure 3. The fungus presents a very rough and undulat- 

 ing surface as though an attempt had been made to form numerous 

 small pilei. The lower side of these nodules bears the nearly verti- 

 cal pores. These, then, are not continuous over the surface but 

 collected in small groups. The uneven appearance of the fructifi- 

 cation may be mostly due to the fact that it is growing over mosses, 

 and some moss fragments can be seen embedded in it. The thick- 

 ness of the fructification is from 2 to 4 mm. There is a distinct 

 brown subiculum from which the nodules arise. The tubes are 

 1.5 to 2.5 mm. long where best developed. Their mouths are 

 rounded and rather small, averaging about 4 or 5 to a millimeter. 

 The dissepiments are thick and entire. There is no sheen or silki- 

 ness to the hymenium. 



The spores are oblong-ellipsoidal or oblong, hyaline, and meas- 

 ure 4.5 to 5.5 by 2 to 2.5 ju (plate 8, figure 5). Setae are abundant 

 and project conspicuously into the lumen of the tube. They are 

 sharp pointed and dark brown in color (plate 8, figure 6). The 

 hyphae of which the subiculum and the trama are composed are 

 dark brown in color and for the most part unbranched. A few- 

 cross walls are present but they are inconspicuous and are easily 

 overlooked. There are no clamp connections on these hyphae. 

 Their diameter varies from 2.5 to 3.5 ^ (plate 8, figure 4). 



A careful perusal of the above facts suggests that the species 

 may not be distantly related to the plant known in this country as 

 Poria ferruginosa (Schrad.) Fries, and the writer is of 

 the opinion that this connection will eventually be established. The 

 unusual habitat and the consequent irregularities of growth are the 

 only separating characters. The shape of the spores is characteris- 

 tic of that species. In fact the writer is unacquainted with any 

 other species of Poria or Polyporus that has spores of this shape 

 and size. The characters of hyphae and setae also agree with that 

 species. P. macouni is not listed by Murrill in the North 

 American Flora where the brown species of Poria are described. 



Redescription. Subiculum effused for several centimeters, the 

 pores collected into vertical groups forming nodules — hence sur- 

 face of fructification very uneven ; general coloration brown ; tubes 

 1.5 to 2.5 mm long, their mouths rounded, ochraceous tawny to 

 tawny, averaging 4 to 5 to a millimeter; dissepiments thick and
