The species Mr. Umemura sends from Japan has small, hyaline 

 spores iy 2 x 4, like the spores of a Rhizopogon. It cannot be either 



of the European species, all of 

 which have large spores 10 mic. 

 or more. It seems to me to agree 

 with Harkness' account of Hys- 

 terangium Phillipsii, though of 

 course all determinations made 

 from descriptions are more or less 

 doubtful. Harkness has a figure 

 showing fibrous rootlets, not on 

 the Japanese specimen, but they 

 may have been broken off. The 

 spores are also given 2x5, which 

 is narrower than in the Japanese, but taken as a whole, the description 

 and figure agree very well with the Japanese plant. 



TRAMETES OCELLATA, FROM REV. TORREND, BRA- 

 ZIL (Fig. 866). This I hold as a form of Trametes hydnoides. No 



commoner plant occurs in 

 the American tropics than 

 Trametes hydnoides with 

 its rigid, black surface hairs. 

 Trametes ocellata is similar, 

 the same as to context and 

 form, but the surface hairs 

 are softer and brown, not 

 black. It is rare, and at 

 first appears quite different. 

 There is a plant in Africa, sim- 

 ilar to Trametes hydnoides, 

 which H e n n i n g s always 

 referred to Trametes hyd- 

 noides. The African plant 

 has always larger pores, and 

 is Trametes hystrix, as 

 named by Cooke. Another 

 (or the same) African plant 

 has still larger pores, then it 

 becomes Hexagona hirta 

 (cfr. Syn. Hexagona, page 

 7). In fact, there is a con- 

 tinued series, all with the 

 coarse, dense, surface hairs, 

 same context color, texture, 

 but differing in size of pores, 

 running as follows, from Tra- 

 jetes hydnoides with minute pores, to hystrix with larger pores, then 

 lexagona hirta still larger, and finally 'Hexagona apiaria with very- 

 large pores. The latter three are African and Eastern plants. Tra-
