CONTEXT AND PORES COLORED. 



i^ijS,,jn part only; and an immaterial part, it seems to me, as the types described 

 under this name are evidently Trametes cubensis. The type of Polyporus supinus is 

 in t'he British Museum. It is so old and changed that we were never sure about it, 

 although we examined it a number of times. At one time we called this species 

 Polyporus subolivaceus, doubting it being supinus. Berkeley usually referred it to 

 Polyporus plebius var. cubensis, and Thiessen lists it as Polyporus plebius. It has 

 no relation to this species. 



A careful reading of Fries' Nov. Symb. leaves no doubt in our mind now as to 

 the plant that Fries had, for we have puzzled long, as Fries evidently puzzled, over 

 the conflicting colors that collections show. Cooke discovered that the plant was a 

 Fomcs, and Morgan determined Fomes pomaceus as being Fomes supinus (sic). 

 Murrill improved on Cooke's idea by calling it "Fomitella." Although faint indica- 

 tions of pore strata are sometimes seen, we are satisfied it is not a Fomes. 



SPECIMENS. Brazil, Anna Brockes, Rev. Rick (four collections), Rev. F. Thiessen, Gustave 

 Peckolt. It is very common in Brazil, also abundant in Florida. We have many specimens from 

 Florida. 



Compare cubensis (var.), guadalupensis, sordidissimus, also Fomes rudis, subfulvus. 



POLYPORUS VALENZUELIANUS. This is the same as Polyporus supinus 

 as to peculiar, olive context and all characters, excepting that it has a reddish brown 

 surface, not white. That it is other than a marked color form we do not believe, 

 but it is biologically distinct, for we noted when growing that they did not intergrade 

 much. 



It is much rarer in Florida than the type form. Montagne called it Polyporus 

 valenzuelianus, which Berkeley referred to Polyporus supinus; and Fries suggests 

 that Polyporus supinus was "discolored" specimens. We use the specific name 

 as understood by Berkeley, Fries, and Montagne as to Montagne's original determina- 

 tion and the specimens he sent to Berkeley and Fries. But the specimen of Poly- 

 porus valenzuelianus listed by Montagne from Weddel, Brazil, is a different plant, 

 with colored spores. The type in Montagne's herbarium from Cuba is not strongly 

 spotted, but the specimens he sent Berkeley and Fries are, and we take it in this sense. 



Compare Fomes sordidus. 



POLYPORUS SUBOLIVACEUS. This has the same context color and is 

 quite close to Polyporus supinus, and the old herbarium specimens can hardly be 

 told apart. Fresh specimens, however, appear quite different. Polyporus sub- 

 olivaceus is unicolorous, with a uniform pileus, surface, and context color, while in 

 Polyporus supinus there is a strong contrast between the context and surface color. 

 We have received from Brazil a specimen agreeing exactly with Berkeley's descrip- 

 tion and, no doubt, with his specimen when it was fresh. This species was named 

 from Cuba, but must be quite rare there, as we noted no specimen in the abundant 

 West Indies specimens at New York. Our note on Polyporus subolivaceus, Letter 

 39, Note 26, and many of our previous determinations, we believe to be in error now 



SPECIMENS. But one collection, from Rev. J. Rick, Brazil. 



TRAMETES PROTEA. Pileus thin, y-\ cm., applanate, sessile, imbricate. 

 Surface smooth, subolivaceus. Context dark olive (Dresden brown of Ridgway), 

 hard, punky. Pores small, paler tissue than the context, decurrent behind. Spores 

 not found, white without doubt. 



It is a question whether this is a Trametes or a Polyporus. Its relations are 

 surely with the preceding plants. In fact, it is so close to Polyporus subolivaceus 

 that the more punky context and larger pores are the only difference.

 Samoa, C. G. Lloyd.
