trama is very compact and in section gives an appearance approach- 

 ing that of the trama of F o m e s c o n n a t u s, but with the walls of 

 the hyphae not quite so thick and the appearance not quite so much 

 like that of a pseudo-parenchyma. The hyphae are flexuous, nearly 

 simple, hyaline, and without clamp connections. Apparently cross 

 walls are lacking (plate 13, figure 2). Their diameter in the subi- 

 culum is 3 to 7 /x, but in the trama they are sometimes slightly 

 smaller, 2 to 5 ^u, in diameter. Small isolated roughened areas are 

 frequent on these hyphae. These areas are not encrusted with 

 crystals but the roughening is apparently due to a breaking and 

 scaling of the hyphal walls. 



According to Doctor Peck the species has a strong disagreeable 

 odor in fresh plants. This has not persisted in the herbariurn 

 specimens. 



The nature of the decay produced can not be determined from 

 the type collection, as no fragments of the substratum are attached 

 to the specimens. 



The affinities of the species are in doubt. The combination of 

 characters presented is quite^ unlike that found in other species of 

 Poria. The plants bear some resemblance to Poria subacida, 

 but are easily distinguished by the much smaller tubes and the 

 much dififerent spores. It also bears resemblance to Poria 

 o r n a t u s but the pores are smaller and the spores dififerent. 

 Specimens previously referred by the writer to P o 1 y p o r u s 

 zonalis as the temperate region form of that tropical or sub- 

 tropical species agree very closely in general appearances with this 

 species. The spores, however, are decidedly dififerent. 



It might be mentioned in this connection that several examina- 

 tions of the type specimens were necessary before spores were 

 obtained. As is often the case in resupinate specimens, the best 

 developed parts of the hymenium showed no spores and in fact 

 no hymenial structure of any sort. It was only when examination 

 was made of those tubes nearer the margin that spores were 

 obtained and the hymenium was found to be well developed. 



Apparently the chief characteristics of the species are the allan- 

 toid spores, the gray pruinosity on the hymenium, the compact 

 trama and the large hyphae. I have seen no other collections of 

 this species and more study is necessary to decide as to whether or 

 not certain factors should be regarded as of specific importance. 

 The dried specimens are not fragile but are quite firm and hard.
