same color, habits, context, texture, pores, and spores. It is a rare form both in Europe 

 and the United States. 



NOTE 279. Cyathus microsporus, from N. L. T. Nelson, Florida. It is very rarely 

 that species of Cyathus are received from the United States that cannot be referred to 

 one of the three common species. This is the second one I have received. The abundant 

 spores are 6-8 mic. which is larger than that of type (4-6). In fact it is Cyathus Hookeri 

 of my pamphlet, but I do not now feel that species based on a slight, spore-size difference 

 should be maintained. Cyathus microsporus is a tropical type, and differs from the usual 

 Cyathus species in its very small spores. 



NOTE 280. Polyporus fumidiceps, from L. Romell, Sweden. This came from Schenec- 

 tady, N. Y., and is the first specimen I have gotten of the species. It is exactly same as 

 Polyporus tephroleucus to the eye but differs in having ovate, transparent, guttulate spores 

 3! /L > x 5. The spores of tephroleucus are allantoid I 1 /, x 5. As the plants are so similar 

 I have gone over the spores of all my collections labeled Pol. tephroleucus and did not 

 find any that were not correctly determined. All have allantoid spores. One must be on 

 the guard however, to distinguish fumidiceps from tephroleucus for there is only a slight 

 spore difference. 



NOTE 281. Polyporus quaitecasensis (?), from Rev. C. Torrend, Brazil. If this plant 

 has been named it is as above. I have mislaid my notes and material of the type, hence 

 cannot compare it. But this plant has the most strongly asperate spores I ever saw in a 

 Polyporus, and is closely related to Polyporus Berkeley!. It was a large species, 20-30 cm. 

 long, and specimen received was only a little piece. There are no notes as to whether it 

 grew on log or tree, or whether it has a stipe or not. I hope it will not prove to be correct, 

 for I should hate to perpetuate such a barbarous name as that. 



NOTE 282. Polyporus asterosporus, from Rev. C. Torrend, Brazil. As named by 

 Rev. Torrend. For me a form of Polyporus rufescens with which it agrees in all macro- 

 scopic characters, to the eye is so similar that I could not believe at first there could be 

 any microscopic difference. Polyporus rufescens is noted for having two kinds of spores, 

 the basidial, globose, 6-8 mic. hyaline, smooth and always abundant ; conidial spores 3-4 

 mic. hyaline, smooth. Polyporus asterosporus agrees also in having the same basidial 

 spores, but the conidial spores same size, are strongly rough. In this connection, I do 

 not doubt that Polyporus Marmellosensis (cfr. Syn. Stip. Pol. 176, fig. 473) also from 

 Brazil, is a form of this same species. I failed to examine its spores, and Hennings does 

 not note whether smooth or rough. 



NOTE 283. "Fomes psila is not rare here. It surely is the Fomes form of Trametes 

 hydnoides." C. Torrend. 



While I am not surprised that Fomes psila is considered a Fomes form of Trametes 

 hydnoides, it is a curious fact that Trametes hydnoides is a very common plant in Florida 

 and Cuba, and Fomes psila has never been found there. 



NOTE 284. "I have no doubt as to the identity of Trametes cupreo-rosea and Trametes 

 Feei. They grow on the same stumps abundantly in Brazil." C. Torrend. 



While the collections I have always seen have appeared very different and I have seen 

 no connecting species, I could accept on sufficient evidence that both are the same species. 

 At the same time it is hard for me to believe from the evidence that I have seen. 



NOTE 285. Polyporus Ballouii, from Rev. C. Torrend, Brazil. Letter 49, Note 118. 

 In the original publication the spores were given too large. I judge 4x5 mic. is the 

 largest spore I note now, which is slightly larger than the Brazilian plant (3 x 4) but 

 surely same species. Since I published a name for the plant I have found that Murrill 

 has a name for it from the West Indies. Polyporus tropicalis, perhaps prior, but not 

 appropriate for a plant that grows around New York City. 



NOTE 286. Polyporus (Amaurodermus) rudis, from Rev. C. Torrend, Brazil. This 

 has soft, spongy flesh, and was not at first recognized by me. On comparison however, 

 I find it same as the Australian species, or at least so close it would not be practical to 

 hold them different. It is very close to Polyporus rugosus, which is the only common 

 species in this section in the East, and it is the first from the American tropics I have 

 seen that is close to the Eastern species. 



NOTE 287. Fomes Ohiensis. (From Rev. C. Torrend, Brazil.) or Trametes as to 

 this collection. It is frequent in the United States, but seems rarer in Brazil. It is 

 quite close but a different species from Polyporus ochroleucus of the East, the only other 

 similar species known. 



NOTE 288 Matula poroniaeformis, from Rev. C. Torrend, India. (Berk, as Auto- 

 creas). A most curious genus considered in detail in Myc. Notes page 390, fig. 228 to 

 230. Heretofore the genus has only been known from Ceylon and Brazil. It has been 

 found in Brazil by Rev. Rick and called Michenen Rompeln. A full history of the plant is 

 given in location cited. 



NOTE 289. Polyporus Sartwelli, from James R. Weir, Montana. Compare Myc. Notes, 

 page 463. I think it is an abnormal form of some other species. 



NOTE 290 Polyporus stipticus, sent by James R. Weir, Montana, as interpreted in a 



pamphlet I no'w have on press on Polyporus. It is a rare plant in Europe and this is
