The best formed ones average about 3 to a millimeter, but appar- 

 cntl\' several adjacent tubes may unite into a single cavity which 

 in extreme instances may be as much as i mm in diameter, or it 

 may be elongated or somewhat sinuous. The walls of the dissepi- 

 ments are thin and in some specimens decidedly dentate, but usually 

 not markedly so. There is no sheen or silkiness to the hymenium. 



The spores are hardly subglobose as described by Peck, but are 

 considerably longer in one direction than the other, and the writer 

 would call them ellipsoidal. When viewed obliquely or from the 

 end they present a nearly globose appearance (plate 12, figure 4). 

 Their dimensions are quite small with a length of .2.5 to 4 /a and a 

 breadth of 2 to 2.5 |U. They are colorless and smooth-walled. The 

 basidia are also quite small, not at all prominent, and not more than 

 2.5 fi in diameter. There are no cystidia (plate 12, figure 2). The 

 hyphae of the trama are loosely arranged so that thin free-hand 

 sections present a very open structure. These hyphae are colorless, 

 2 to 3.5 ju in diameter, and frequently branched, the longitudinal 

 axis of the branch always being at nearly right angles to that of 

 the hyphae from which it is produced. All branches originate near 

 cross walls (plate 12, figure 3) and the first cell of the lateral branch 

 is rather short, rarely 10 fx, long; a cross wall with a clamp con- 

 nection is then produced and the next cell is much longer. Clamp 

 connections are quite abundant. In the subiculum the hyphae are 

 more irregular and, especially on the growing margin, coalescing 

 strands of all sizes are seen to be forming the larger mycelial cords 

 visible on those portions of the fructification. 



According to the original description reproduced above, the type 

 collection was taken from hemlock wood at Round Lake, Saratoga 

 CO., N. Y. August 21, 1900. But the label on the sheet containing 

 the herbarium specimens gives the locality as Floodwood, N. Y. 

 Dr H. D. House, the present State Botanist of New York, has 

 noticed this discrepancy and has attached the following typewritten 

 note to the sheet. 



" The type locality of Poria myceliosa Peck as given in 

 Mus. Bui. 54, p. 952-53. 1902 (viz, Round Lake, Saratoga co.) is 

 not correct. Doctor Peck's private notes show that the species was 

 collected at Floodwood on August 31, 1900, and his notes of that 

 date contain the preliminary draft of the description of Poria 

 myceliosa." 



The species is rather closely related to Poria fimbria- 

 t e 1 1 a Peck, which differs conspicuously in the presence of dis-
