SPORES HYALINE. 



NOTE. We have a collection from Rev. Rick, Brazil, which has been referred to Polyporus 

 nivosus, but which on comparison at Kew seems different. The abundant spores are globose 3 'A mic 

 irregular. Not found by us m type of Polyporus nivosus. Color of flesh deeper yellow than in 

 nivosus. 



POLYPORUS CREMEUS. This has same color, texture, pores, and abundant 

 cystidia as Fomes connatus (which see in Fomes pamphlet), but the spores are 

 globose, Sy,. mic., about one half the size of those of Fomes connatus. It was first 

 referred to a Polyporus form of Fomes connatus, afterwards named in mss. as 

 above. I have several collections from Rev. Rick, Brazil. 



POLYPORUS CAESPITOSUS. Pileus white, sessile, imbricate. Surface 

 dull, no distinct crust. Context hard, white, about 2 mm. thick. Pores minute, 

 white, 1-2 mm. long. Spores (teste author) ovoid, 5x7 mic. 



The pilei are about 2 x 3 x ^ cm., and imbricate (rather than caespitose). 

 The plant is only known from Philippine collections, but why referred to "Trametes" 

 is a mystery to me. 



POLYPORUS ELLISIAXUS. Pileus effused, adnate with triquetrous, rigid 

 pileus. Surface uneven, smooth, hard, brown. Context hard, white. Pores small, 

 round, drying darker than the context. 



Known from one collection in Ellis' herbarium, which he found on pine. It 

 impressed us as being a good species, although we have but a slight recollection of it. 



Compare Polyporus osseus, Stipitate Polyporoids, page 191, fig. 496, which is imbricate, 

 but has the pileus reduced to a small attachment. It might be sought in this section. Compare also 

 Brenningii and obducens in the synonyms. 



B. Surface strigose with brown hairs. 



POLYPORUS SETIGER. Pileus dimidiate, sessile (3x4x1 

 cm.) Surface hispid, with short, brown, strigose hairs. Flesh firm, 

 white, hard. Pores small, soft, fragile, discolored (in drying, no doubt). 

 Spores allantoid, 1x4, curved. 



In Europe or the United States there is no species similar to this 

 with white flesh and brown, strigose pileus. The types are from New 

 Zealand, at Kew, and only known from one collection. Polyporus 

 atrostrigosus, also from New Zealand, but known from scanty ma- 

 terial, is very similar and probably the same species. 



Compare atrostrigosus. 



The three following divisions differ from the usual type of related plants so much that a "new 

 genus" could be based on each of them. 



C. Spores large, hyaline, truncate, corresponding to "Ganodermus" spores. 

 Fomes Ohiensis is the only other known species with similar spores. 



POLYPORUS OCHROLEUCUS (Fig. 651). Pileus usually 

 well formed, regular, ungulate (3x4xl>^-2 cm.) Surface with in- 

 distinct crust, smooth, or more or less appressed, strigose, fibrillose, 

 faint indications of zones. Color usually pale, with a slight ochraceous 

 tint, rarely decidedly yellowish. Context thin, hard; at first pale, in 

 old specimens becoming dark. Pores small, % mm., regular, long,
