slightly pruinose and tinged with flesh color ; the yellowish mycelium 

 or subiculum penetrating the matrix. 



Decaying wood. Oneida. H. A. Warnc. 



This species is remarkable for the peculiar character of the pores 

 which form little cells or cavities instead of tubes, so that in what- 

 ever direction the mass is cut or broken, the section appears equally 

 porous. Perhaps this character will necessitate the formation of a 

 new genus. 



Notes. This plant was originally placed in the genus Polyporus 

 but was later transferred to Myriadoporus, a genus erected by Peck 

 to receive what are now believed to be abnormal forms of other 

 species, differing from well-developed specimens in having a cellu- 

 lar, hymenial surface that is usually sterile. In such specimens 

 both vertical and cross sections of the hymenial region show dis- 

 tinct pores or cavities. 



The writer does not believe that the present species deserves 

 specific rank because of its apparent abnormality. But the absence 

 of a hymenium is more or less of a barrier to deciding of what 

 species it is an abnormal form. Nevertheless, others may not agree 

 with the writer, and hence a description is here appended, based 

 entirely on the type collection. 



There are mounted on the type sheet at Albany five small speci- 

 mens of the fungus, the largest of which is only about 3 cm long. 

 The specimens are annual and belong to the white group of Poria 

 (plate 6, figure 6). At present the hymenial surface is avellaneous 

 or vinaceous buff or verging toward pinkish cinnamon. The margin 

 is abrupt, rather thick, and nearly or entirely fertile. The thickness 

 of the hymenium-producing portion is 3 to 6 mm, of which the 

 subiculum is a rather thin and inconspicuous part. The cellular 

 hymenium is 2 to 5 mm thick, but the tubes are not continuous in 

 any one direction. At whatever angle the hymenium is cut they 

 appear as small rounded holes, averaging 5 or 6 to a millimeter 

 (plate 7, figure 3). 



The type material is sterile, and for the most part does not con- 

 tain either basidia, cystidia or paraphyses (plate 7, figures i and 2). 

 The trama is very compact and made up of thick-walled hyphae 

 which in cross section give a firm pseudo-parenchymatous appear- 

 ance to the trama (plate 7, figure 2). When teased out the hyphae 

 are seen to be hyaline, mostly simple, and with few apparent cross 

 walls. Their thickness is 5 to 7.5 fi, and the walls are often as much 

 as 2 /A thick (plate 6, figure 7).
