ville. This appears to be the same species, and if so is in a much 

 better condition than any of the others. The color is pale ochraceous 

 salmon or light pinkish cinnamon. According to Peck, the fresh 

 specimens are whiter and with a tinge of lilac to the subiculum. 

 Most of the specimens are broadly sterile on the margin, sometimes 

 as much as 4 or 5 mm. This border is finely tomentose but scarce 1 y 

 fimbriate. On some specimens from the type locality and grow in ; 

 on beech leaves, a few white rhizomorphic strands are developed. 

 They are not present where the specimens grow on wood. The 

 thickness of the hymenium-producing portion is less than one-half 

 of a millimeter in the dried specimens. The subiculum is extreme 1 ) 

 thin and the tubes very short, appearing scarcely more than shallow 

 depressions in the dried specimens. The mouths of the tubes are 

 more or less rounded but unequal in size, averaging about 3 to a 

 millimeter. Peck states that the dissepiments are toothed on the 

 edge. The writer would not describe them as toothed in the sens: 

 that the term is ordinarily used as applied to inequalities arising from 

 lacerations of the dissepiments, but they are slightly uneven because 

 one edge of the tube is slightly prolonged beyond the other. The 

 dissepiments are rather thin but entire. There is no sheen or 

 silkiness to the hymenium. The spores are oblong or short cylindric, 

 hyaline, and 3 to 4 /x long by 2 /jl broad (plate 17, figure 6). So far 

 as the writer can ascertain from Peck's collections, they are never 

 allantoid at maturity as in Poria g r i s e o a 1 b a , but in other 

 respects they resemble very much the spores of that species. The 

 basidia measure 2 to 3 fx in diameter. There are no cystidia in the 

 hymenium of most specimens (plate 17, figure 3) but in the Lyndon- 

 ville collection they are sometimes present as projecting, weakly 

 encrusted hyphae near the mouths of the tubes. The subiculum is 

 rather open in construction, and made up of hyphae that are thin- 

 walled, flexuous, branched, and with rather prominent cross walls 

 that separate the filament into elongated cells (plate 17, figure 5). 

 These are never so short as those frequently found in Poria 

 griseoalba, but they are always many times as long as broad, 

 though the dimensions do not appear to be very constant. In the 

 trama the hyphae rarely reach the diameter of the larger ones of 

 the subiculum and at times cross walls are difficult or impossible to 

 make out (plate 17, figure 4). These hyphae vary in diameter from 

 3 to 7 (i, and hyphal fusions are extremely common. There are no 

 clamp connections on the hyphae. Rarely they are very slightly 

 encrusted with small, scattered granules but these are not noticeable
