NOTE 65. Polyporus obtusus, as received from Prof. Fetch, Ceylon. The finding 

 of this plant in Ceylon by Prof. Petch is quite remarkable. It is fairly a frequent plant 

 in the United States, but known in recent times from but one collection (Kmet) in 

 Europe. It only occurs in the East of Europe, and was originally found by Schulzer in 

 Hungary. It appears in Fries' Hym. Europae as Polyporus Schulzeri and the identity 

 of the European and American plant was recently suggested by Mr. Murrill, and I think 

 it is correct. While there are a number of specimens from the United States in the 

 museums of Europe, I believe there is but one from Europe (viz. Kmet), and the collection 

 of Prof. Petch is the first known from the East. 



Berkeley described the plant as Polyporus, then he transferred it to Trametes inci- 

 dentally in a paper somewhere, but it was overlooked by Cooke and Saccardo and the 

 plant has always appeared as .a Polypoms. It is a question whether it is a Trametes 

 or Polyporus, just as it is a question how to define Trametes. 



NOTE 66. Xylaria hypoxylon, specimen from John Macoun, Vancouver, Canada. 

 In the United States I have only observed this species from the extreme Northwest. 

 We have a very common plant, usually so determined, but I think in error. Our common 

 plant does not in my opinion agree with Xylaria hypoxylon so common in Europe. 



NOTE 67. Polyporus hirtus, specimen received from John Macoun, Vancouver, 

 Canada. This is the first specimen I have ever received. It is quite a rare plant in 

 the United States and the only two collections I have previously seen from the United 

 States were in Peck's collection at Albany. Peck called it a new species, Polyporus 

 hispidellus, but it is the same as a rare plant named in Europe. It is peculiar in its 

 spores (cfr. Stipitate Polyporoids, page 130). The stipe in this specimen is not as 

 strongly lateral as shown in our figure (426). 



NOTE 68. Polyporus varius, sent by George E. Morris, Waltham, Mass. In America 

 this typical plant of Europe is rather rare, but Mr. Morris' plant seems exactly same 

 as type form in Europe. Our common form, which we call Polyporus picipes, is really 

 only a geographical form of varius of Europe, but is a thinner plant and of darker color. 



NOTE 69. Hydnum cyaneotinctum, from George E. Morris, Waltham, Mass., is 

 probably the same as Hydnum compactum of Europe and also Hydnum caeruleum. I note 

 in the herbarium at Kew, American specimens referred to Hydnum compactum by 

 Berkeley, Farlow, and Ellis. It is very close also to suaveolens, which, like it, turns 

 blue when cut. 



NOTE 70. Hydnum niger, from George E. Morris, Waltham, Mass. I have long 

 thought that our American plant must be the same as the European species, and a 

 comparison at Kew of Mr. Morris' species with the freshly collected English material 

 fully confirms this. 



NOTE 71. Hydnum (sp.), from George E. Morris, Walthnm, Mass. This has a 

 very peculiar color, greenish yellow, but unnamed as far as I know. I have seen a 

 specimen of this same plant in Peck's herbarium determined as Hydnum geogenium of 

 Europe. This has a similar color, but the European species is entirely different in its 

 mode of growth. Good specimens of geogenium are at Upsala. There is also a cotype 

 (from Fries) at Kew, but it is old and has lost all its distinctive color. 



NOTE 72. Libellus, a new genus of Thelephoraceae. Pileate with a central stipe. 

 Pileus, thin like a sheet of paper, with hymenium on the lower side. Hymenium even, 

 smooth, without cystidia. This is basod on a plant named by Berkeley Craterellus 

 papyraceus. The genus differs from Craterellus in the very thin, fragile pileus, which 

 can be likened to a sheet of paper. 



Libellus papyraceus, Berkeley. Pileus horizontal, smooth, thin, less than a mm. 

 thick, 7cm. width, membranaceous. Color, bright red. Hymenium on the lower surface, 

 smooth, glabrous, color yellowish brown when dry, bright red when fresh. Stipe meso- 

 podial, slender, equal, 9 cm. long, 3 mm. thick, dark brown, glabrous. Cystidia none. 

 Spores or basidia not found. 



This is a most striking and peculiar plant; no other, as far as I know, is in any 

 way similar. The nearest seems to be the genus Helioiayces, which, however, has a 

 viscid hymenium, belonging to the Agaric series. It is only known from the type at 

 Kew, a single specimen, collected by Fendler in Venezuela. Smith gave : striking picture 

 of this plant in the British Journal of Botany, but I have misplaced the reference, and do 

 not recall what name he used. At any rate, Berkeley corrected it, and it was overlooked 

 in Saccardo. 



NOTE 73. Fomes angulus, from Jintaro Umemura, Nagoya, Japan. Pileus angular, 

 semiresupinate, small (2-3 cm. wide, 1-1% cm. thick). Surface black, hard, with narrow, 

 raised zones. Context hard, dark, ferruginous. Pores minute, with narrow, annual 

 layers (1 mm.). Pore mouths concolorous. Setae none. Spores not found, no doubt 

 hyaline. 



This species is unusual in the angular, subappressed, zonate pileus. In context 

 color and microscopic characters it approaches Fomes igniarius. Type (No. 78) from 

 Jintaro Umemura, Nagoya, Japan, growing on Pasania, which is allied to Quercus and held 

 by some t6 be the same genus.
